Special PCB, in fact, can also be classified to Metal Core PCB or FR4 PCB, if we sorted PCB by board material. Considering the specialrequirements of these different boards, such as High Frequency, 10 oz heavy copper, buried & blind unique, we name it as "Special PCB".

Right now, we can make various special printed circuit boards, but not limited to:

High frequency RF boards: RF board us Rogers, Taconic or other high frequency materials and normally, the frequency is between 300MHz ~ 3GHz, or much bigger;
High Tg PCB: Tg value of board material is 170~210 Degree. Tg value of normal FR4 board is about 130~150 Degree.
Heavy Copper PCB: copper weight is 4~10 OZ/ft2, and 20~200 OZ/ft2 refers to extreme heavy copper printed circuit board;
Ceramic PCB: has excellent high pressure, high insulation, high frequency, high temperature, and high reliable and minor volume electronic;
HDI PCB: with buried & blind via, drill layer up like: 1-2-1, or 2-4-2, need laser drilling, and PTH <=0.1mm;
Beside from above requirements of PCB, we can also make other special boards, such as :

Impedance controled PCB: 50 ohms, 100 ohms, in outer or/and inner layer and tolerance can be +/-10%;
Carbon ink PCB: The resistance of carbon in can be normal as 100 ohms, 500 ohm, or as high as to 10,000~500,000 ohms;
Other special Printed Circuit Boards.
Whatever you need, we will work together with you, and do our best to make it come to a real board. To be your best partner for MCPCB, FR4 PCB and Special PCB is the goal we are continued working for.

Busbar PCB is an electronic component, also known as a socket board or mother board, which is an important part of an electronic device and is used to connect and transmit current and signals, so it plays a crucial role in the design of electronic devices. Busbar PCB is like a PCB coated with an “ear”, which we also call it as stiffener busbar. Want to know more about it? Welcome to reading on!

What is PCB Bus bar?A busbar circuit board is a key component used in electrical systems. Some people call it as bus bar PCB or embedded bus bar PCB. It usually consists of a main conductive busbar (usually copper or aluminum) that is covered with an insulating material such as prepreg or resin. Busbar boards are used to transmit high currents in power systems, such as in industrial equipment, power distribution systems, and control panels.These boards typically have multiple slots for inserting electrical connectors or electrical devices. The design of the bus board can be customized according to the specific application requirements to adapt to different current and voltage requirements. They are widely used in the industrial and commercial sectors because they provide reliable power transmission and connectivity solutions.

An extra thin PCB is a type of printed circuit board that is significantly thinner than a standard PCB, which typically has a thickness ranging from 1.0 mm to 2.0 mm. Extra thin PCBs, on the other hand, have a thickness of less than or equal to 0.6 mm. Those with thicknesses between 0.1 mm and 0.4 mm are specifically referred to as extra thin PCBs.

But sometimes, limited to space or margin, or needed by design purpose, people need extra thin such as 0.25mm, 0.20mm, or even 0.15mm board. For providing customers with the most suitable products and the most satisfactory services, Best Technology also made the extra thin printed circuit.For 2L FR4 PCB, we are able to make it to 0.15mm±0.1mm. Then you can use it in SIM card, sensor card and so on. As shown, it can also be rotated 180 degrees.

Why use extra thin PCB?
In certain applications, space constraints or design requirements necessitate the use of thinner PCBs. For instance, extra thin PCBs with thicknesses like 0.25 mm, 0.20 mm, or even 0.1 mm are ideal for use in SIM cards and sensor cards. The growing market demand for slimmer, more portable, and lighter devices has driven the widespread application of extra thin PCBs.

Extra thin PCBs can be manufactured in various thicknesses such as 0.15 mm, 0.20 mm, 0.25 mm, and 0.30 mm, with or without a solder mask. The copper thickness can range from 1/2 oz to 3 oz. These PCBs come in a variety of materials, including flexible core materials, FR4 core materials, BT core materials, and other specialized PCB materials.

Since established in 2006, Best Technology is always dedicated to provide the most suitable products and the most satisfying service for customers, to be customers’ best partner of PCB and PCBA in China.

HDI abbreviation means High Density Interconnect. HDI PCBs have extremely density trace spaces and lines, micro vias under 0.25mm(10mil), smaller pads and higher connection pad density. See the photo of HDI board laser drill & prepreg thickness ratio.

It is very helpful in enhancing electrical performance and HDI PCB use for high-end products and HDI PCB is regularly used in 5G network communications, medical, Military and Aerospace. HDI PCB is the better option for high-layer count and costly laminated boards. Due to the increasing complexity of design structures laminate, the Blind vias and Buried vias are increasingly used in high-density circuit boards (HDI PCB board).

What are benefits of HDI PCB?
HDI boards often utilize blind and buried vias, which are vias that do not extend through the entire board. Blind vias connect an outer layer with one or more inner layers, while buried vias connect inner layers only. These vias help optimize space and increase routing capabilities. Additionally, HDI boards support the use of fine pitch components, such as microcontrollers, ball grid array (BGA) packages, and small surface-mount devices (SMDs). The high routing density and smaller features of HDI boards make them suitable for accommodating these tiny components.
How to design a HDI printed circuit board?
Designing HDI boards requires expertise in factors such as layer stacking, via types, trace widths, and clearances. Advanced design software and manufacturing techniques are often employed to ensure precise alignment and reliability of the intricate interconnections.
However, HDI boards can be more challenging to manufacture compared to standard PCBs. The use of smaller features and complex layer structures requires specialized fabrication techniques, such as laser drilling, sequential lamination, and precise registration control.
