Choosing the Right Custom PCBA Manufacturer: Key Considerations

Choosing the Right Custom PCBA Manufacturer

PCBA is short for Printed Circuit Board Assembly, which means the process of soldering or assembling different components of electronics on a Printed Circuit Board. It forms one of the bases in the realm of electronics. 

Essentially, PCB is a board made of non-conductive material and copper traces mainly. Copper trace provides ways of electric current flow hence enabling interconnections of various electronic devices in a manner that is well defined and controlled. The PCBA process starts after having designed the PCB layout and manufacturing the board. The PCB board itself is the platform on which several electronic components are mounted, which include but are not limited to resistors, capacitors, transistors, and integrated circuits. 

In the PCBA process, Surface-Mount Technology (SMT) and Thru-Hole Technology (THT) are the most common techniques used in the industry for the connection of the components. In SMT technology, the component is directly mounted above the surface of the board. On the other hand, in THT technology, the leads of the component are inserted into previously drilled holes in the board, after which they are soldered in place.

What is a Custom PCBA Manufacturer

To know a custom PCBA manufacturer, we need to know what is custom PCBA first. Custom PCBA is short for customized printed circuit boards. Unlike ready-made PCBAs, custom PCBAs are built specifically according to the unique design for any electronic device, it is widely used in a lot of areas, such as industrial, energy, power, control, robotics, medical, automotive, telecommunication, and wireless., etc. 

A custom PCBA manufacturer is a PCB assembly supplier who produces and assembles PCBs to customers’ own design. The PCBs are designed by customers’ engineers to meet their specified functions. Generally speaking, PCB Gerber files and a BOM list will be needed to produce a custom PCBA.
