Measures China took to fight against the COVID-19
Tuesday, March 31st, 2020

China’s fight against COVID-19 epidemic has achieved victory at this stage. Infected patients were found in 337 cities in China but now only 28 cities remaining patients in cure. So far till March 31st, there were 82545 confirmed cases in China, while 76225 cured and only 3006 remaining now. Most importantly, many of the areas finds only one figure number increase and others stop increasing for quite some days. If the first half of COVID-19 fighting is inside China national territory, the second half will be on the international stages while noticeable growth on COVID-19 infected cases are spreading all over the world now.

Best Technology has been collecting the measures in China on epidemic controls so in order to provide a more objective and useful reference for overseas professionals which we hope they could refer to and protect better themselves from the COVID-19.

Governmental Measures

During the height of the outbreak, trains didn’t stop at the disease’s epicenter, Wuhan

Trains, as well as other tightly packed forms of transportation, can serve as vectors of illness. The more people, the more closely packed, and the more poorly ventilated the space, you can imagine that’s a bad situation because there are a ton of people, they’re in very close quarters, and they’re a totally captive audience. Cutting off transportation was considered on the top three measures to contain the spread of the virus.

China built new hospitals in a rush, with workers toiling night and day to get them done.

China built two new 1,000-1,300-bed hospitals to fight the corona virus, one created in six days, and the second in 15 days, using prefabricated modules.

Corona virus testing was easily accessible and free

In China, patients who were confirmed to have the corona virus were either sent to an isolation center or hospital. The government also made clear that testing for the new virus was free, and COVID-19-related charges that weren’t covered by a person’s insurance would be paid for by the government.

The country implemented large-scale contact tracing in the early 2000s

Contact tracing

During the SARS outbreak in 2002-2003, China set up large-scale surveillance systems that included contact tracing, a front-line public-health strategy that involves identifying and following up with people who may have come into contact with an infected person.

The country postponed non-urgent medical care and moved many doctor’s visits online. Not all patients were given the critical care they needed during the outbreak, though

In China, elective surgeries and other non-critical doctors’ visits were delayed, and many medical services were moved online. Someone in one place said 50% of their consultations are now done online; they just moved a whole bunch of what was normally done physically online to be able to keep the regular health services going.

Centers for Disease Control exploring a way of therapeutic plan combing Traditional Chinese medicines and Western medicines.

The combination of Traditional Chinese medicines and Western medicines had been proven effective on the SARS fights. Doctors of traditional Chinese medicines had volunteered for consulting and participating into the virus fights.

China used technology that aims to trace every single COVID-19 case

Civilian Measures

Traditional epidemic prevention manufacturers speed up and similar production lines integrating to make more necessary products

Many medicinal and pharmaceutical substances manufacturers launched automation assemble lines and increase manpower to speed up the mass production of necessary drugs, masks, ventilators to meet the huge consumption during virus fighting. Many of these companies arranged 24-hour shifts for maximizing the production.

Meanwhile other manufactures such as automotive OEM had change their assemble line into masks productions machines.

At the blast of COVID-19, returning Chinese carrying back epidemic products from overseas as much as they can

 Returning travelers carried extra masks on their flights back to China and donated them to the hospital and governments in need. Some overseas Chinese unions also had helped ordering these products and sending to China.

Chinese citizens did their part to curb the disease’s trajectory on an individual level, too, though we may never know the true scale of their complaints or sacrifices in this outbreak.

China's road

In contrast to reports in the US of people clamoring over the last hand-sanitizer, the attitude of people in China was that they were all in this together. People stay at home for self-quarantine, lockdown and response to the postpone returning to work and school.

People who thought they might have the corona virus could go to one of the nation’s many fever clinics

People who thought they had the novel corona virus in China would often be sent to a special fever clinic, which have been widespread since the country dealt with an aggressive SARS outbreak in 2002. Their temperature would be taken, and they’d discuss their symptoms, medical history, travel history, and any prior contact with anyone infected with a doctor.

If necessary, patients might receive a CT scan, which is one way to do an initial screening for COVID-19. Each machine did maybe 200 a day. 5-10 minutes/scan. A typical hospital in the West does one or two an hour.

People quickly shifted jobs in order to assist during the outbreak

volunteers

When it came to the non-medical response, there was a nationwide sense of solidarity with Hubei. Other provinces sent 40,000 medical workers to the center of the outbreak, many of whom were volunteers.

Workers in transportation, agriculture, and clerical positions were encouraged to new positions such as delivery, courier and epidemic prevention manufacturing, too.

While staying home, it’s been relatively easy for Chinese people to get extra food and supplies

Enough food
Enough food

China essentially mandated a country-wide shut down, demanding that every Chinese resident stay home until the curve was flattened. But in West, unlike China, a country-wide shutdown would be difficult to enforce.

Fifteen million people had to order food online. It was delivered. Yes, there were some screw-ups. But few said: every now and again there’s something missing from a package, but food supply is pretty much normal via ordering online.

We know it’s difficult for most of people around the word to find protection devices, such as face mask, Non-surgical isolation gown , Medical gowns, protective coveralls, Surgical Cap, Surgical Dress , Medical gloves, Safety Goggles, Surgical Helmet, infrared thermometers, please contact our sales, we will be glad to support you.

Do You Ever Know High Density Interconnect PCBs?
Tuesday, December 31st, 2019

HDI PCB (High Density Interconnector PCB), is a printed circuit board having a relatively high line distribution density using the micro-blind and buried hole technology.

It is a process that includes an inner layer line and an outer layer line, then uses a hole and a metallization in the hole to realize a joint function between the inner layers of each layer.

HDI PCB-1
HDI PCB-1

With the development of high-density, high-precision electronic products, the requirements of high-density and high precision are imposed on printed circuit boards. The most effective way to increase the density of pcb is to reduce the number of through holes, and to accurately set the blind holes and buried holes to achieve this requirement, thereby an HDI PCB came into being.

HDI PCBs are finding their way into a growing number of products:

Military communications devices and other strategic equipment

Aerospace – smaller space requirements and light weight are ideal for such applications

Computers and smartphones – phones and computers are taking full advantage of smaller profiles, reduced weight, and increased functionality, made possible through the integration of HDI circuits.

HDI PCB-2
HDI PCB-2

Medical equipment – diagnostic and monitoring equipment has become more reliable and expanded with technical features that aid medical teams with patient treatment, and all of this is powered by HDI PCBs and advanced software.

Benefits of HDI PCB

HDI PCB utilizes buried or blind vias, or a combination, and may also incorporate microvias with an incredibly small diameter. This facilitates the incorporation of more technology in less space, with fewer layers. Multi-layer HDI PCB are also in common use, with many layers being accommodated through various construction methods utilizing blind, buried, stacked, and staggered vias.

With smaller components and blind via in pad technology, components may be placed closer together, resulting in faster signal transmission rates while also reducing crossing delays and signal loss. These are key considerations that generate improved performance of HDI PCBs.

HDI PCBs are preferred for applications where space, performance, reliability, and weight are concerns. This makes them more suitable for nearly every application related to electronics, consumer products, computers, and aeronautics.

Multi-layer HDI PCB can provide strong interconnection of stacked vias, resulting in high levels of reliability, even in more extreme environments.

Considering this, do you ever think about choosing HDI PCB on your next project?

LED Lighting: MC-PCBs
Wednesday, November 13th, 2019

LEDs are pretty hot nowadays! Not just the biggest tendency in lighting, but also require a lot of heat dissipation that standard PCB material just can’t handle. So what’s the solution? Metal PCBs. Standard PCB material typically has a thermal conductivity of 0.5 W/m K; which is not adequate for the current high intensity LEDs. With MCPCB materials you can increase the life of your LEDs with better heat dissipation.

What’s the thermal conductivity of MCPCB material?

Up to now, Best Technology has helped many customers with their MCPCB needs and have found the most common questions as shown below:

What is the most cost effective MCPCB?

How do you layout an MCPCB?

Can I get a different dielectric thickness between the metal and circuit layer?

Can I put plated through holes on an MCPCB?

Can I do more than one layer with an MCPCB?

How quick can a MCPCB be manufactured?

What Metals can be used?

PCB Assembly Fabrication Methods
Tuesday, November 12th, 2019

PCB or Printed Circuit Board assembly at Best Technology involves combining the bare PCB, electronic components, and other accessories effectively to allow the assembly to function as the designer intended. Generally speaking, the fabrication methods involve a number of major steps:

(1)Component placement

(2)Soldering

(3)Cleaning

(4)Inspection

(5)Testing

Component Placement

Methods of placing components on the PCB rely on several factors such as:

Single or double side component placement

SMD components only

Through-hole (TH) components only

Mix of SMD and through-hole components

A PCB may have components present only on one of its sides or on both, although assembling a PCB with through-hole components on both sides is a rare occurrence. Single side component placement with either all SMDs or all through-hole components is more common, while single sided PCBs with a mix of SMDs and through-hole components is also to be found.

For assemblies requiring SMDs on both sides of the PCB or a mix of SMD and through-hole components on the top and only SMDs on the bottom, the PCB assembly process must be broken up into several intermediate steps, and the assembler needs to take special precautions for each of them.

Soldering

Soldering is the process of joining two dissimilar metals using a molten filler metal alloy. The molten metal alloy enters the joint, and as it cools and solidifies, bonds with the adjoining metals. Primarily,  three common ways of soldering including manual soldering, wave soldering and reflow soldering are available.

Cleaning

After soldering is over, some flux residue may remain on the printed circuit board. Over time, this can turn acidic, and corrosively damage solder joints. The flux residue can also attract fingerprints and make the PCB look unclean.

Manual Inspection

Inspection is necessary at various stages of assembly. For instance, one stage of inspection is necessary when the operator has stuffed TH components into the board, and again once the assembly has undergone wave soldering.

Similarly, for reflow soldering, inspection is necessary once after solder paste printing is over, then again after mounting the SMD components, and once again after the boards have exited the reflow oven.

AOI & X-Ray Inspection

For large batches of PCB assembly, the manual inspection process may be too slow. A faster process is the Automatic Optical Inspection or AOI process. AOI machines have video cameras to capture images of the PCB, the components, and the solder quality, and they can compare the images with standard images in the machine’s memory. The AOI machines work at high speed processing a large number of PCBs within a relatively short time.

Electrical & Functional Testing

Electrical testing may be necessary after the assembly has passed through the above stages, to test whether the assembly functions as intended by the designer. This may involve programming the board, or calibrating certain components before the actual testing can begin.

Electrical and functional testing involves applying specific voltage/voltages to the circuit on the PCB and looking for normal/abnormal behavior at predefined outputs. Some tests may require a voltmeter and ammeter, while others may need more sophisticated instruments such as an oscilloscope or a waveform analyzer to complete the testing.

Conclusion

PCB assembly is a complicated process involving several technical processes with important setup parameters. Eminent assemblers such as Best Technology are always careful with these setup parameters to allow the final product achieve the desired quality.

The Basics of Printed Circuit Board Assembly(SMT)
Friday, November 1st, 2019

Printed circuit board assembly(SMT), also known as “stuffing†or “populatingâ€Â the bare printed circuit board, is quite an intricate process which involves many different stages.  Best Technology’ in house printed circuit board assembly service makes ordering your turnkey printed circuit boards a hassle-free experience as you can count on the industry’s largest support team to help you control every step of the process.

Here are some of the basic elements involved in the printed circuit board assembly process:

Solder Paste Ã¢â‚¬â€œ Solder paste is a combination of flux, a chemical created to assist in the bonding and melting of the metal, and small fragments of metal (solder) so as to apply the electronic components to the printed circuit board. The paste is placed on the board in specific places along the board in exact amounts with the use of a Solder Stencil and a paste application machine, automatically.

Pick and Place Machine – This machine is essential in an automated printed circuit board assembly process.  The machine is programmed to automatically coordinate with complete accuracy the places to precisely mount each electronic component to be soldered to the printed circuit board. These machines are exact and quick.

Infrared Reflow Ã¢â‚¬â€œ After the precise bonding element (solder paste) is applied to the PCB, the board will be directed to the reflow oven to join the electronic components to the board by melting the solder paste. This “oven†is comprised of many heaters whose main function is to heat the board to a precise temperature and control the level of cooldown as the solder hardens. This process is crucial to the creation of properly functioning electronics. The printed circuit board will run through a series of testing to ensure no issues or short-circuiting nor misalignments have occurred.
