As a premier expert in PCB, Best Technology is always striding to catch up the step of times. We try our best to apply advanced technology in the PCB manufacturing. Press-fit cold-solder technology from Best Technology explains some details about designing guide and benefit of PCB using press-fit technology pins & connectors to realize PCB solderless.

1.Press-Fit Pin

Press-fit pin is an alternative to the soldering method and connectors which is pressed through properly dimensioned plated-through holes on a printed circuit board.

2.Press-Fit Connectors

There are different types of press-fit connectors for PCB, including those with solid pins (which don’t contort during insertion) and compliant pins (which compress or ”comply” during insertion).

3.Benefits

Here are benefits and advantage of using press-fit technology components in PCB such as reducing PCB assembly time and effort considerably, eliminates costly additional soldering in PCBA.

4.Application

Press-fit connectors are utilized in all sorts of applications, from data and communication to transportation and mechanics, within the industry segment, like the drive, solar and UPS market, a demand for improved reliability can be observed.

5.Specification of PCB Using Press-in Cold-Solder Components

According to the IEC 60352-5 standard, there are some requirements referring to the PTH of the PCB. On the one hand this ensures the proper functioning on the other hand Best Technology did all qualification tests with these values.

6.Components Next to Module Pins

Best Technology recommends to leave at least 4 mm between the edge of these SMD components ( resistors, diodes or capacitors) and the middle of the PTH using press-fit technology. This ensures enough space for the pressing tool to back the PCB.

7.Some Notes

Nowadays modern Press-fit pins contain a compliant mechanism that allows plastic deformation when the pin enters the hole. This compliance compensates the whole size tolerance, helps to prevent damage the PCB, keeps spring force for long term and permits repairs.
