How to Select the PCB Material for Your Design
The advent of 5G cellular communication networks has sparked discussion about building fast digital circuits all around the world. Engineers are searching for the best ways to transmit signals and frequencies through the current standard materials for printed circuit boards (PCBs). The goal of all PCB materials is to transmit electricity and provide insulation between copper conducting layers. The...

How to Choose the Right PCB Manufacturer
How to Choose the Right PCB Manufacturer It is not always simple to select the best manufacturer for a printed circuit board (PCB). After developing the design for the PCB, the board must be manufactured, which is typically done by a specialist PCB manufacturer. Choosing the right PCB manufacturer can make the process much easier, but choosing the wrong one can cause a lot of problems. Depending o...

Rigid PCB vs. Flexible PCB
Rigid PCB vs. Flexible PCB Both rigid and flexible printed circuit boards are types of printed circuit boards. The rigid PCB is the traditional board and the foundation upon which other variations arose in response to industry and market demands. Flex PCBs revolutionized PCB fabrication by adding versatility. ABIS is here to help you learn about rigid vs. flexible PCBs and when it's better t...

How to avoid printed circuit board warping?
How to avoid printed circuit board warping 1. Reduce the effect of temperature on board stress Since [temperature] is the main source of board stress, as long as the temperature of the reflow oven is lowered or the speed of the board heating and cooling in the reflow oven is slowed down, the warpage of the PCB can be greatly reduced. However, other side effects may occur, such as solder shorts. 2....

COB
Since COB does not have a lead frame of IC package, but is replaced by PCB, the design of PCB pads is very important, and Finish can only use electroplated gold or ENIG, otherwise gold wire or aluminum wire, or even The latest copper wires will have problems that cannot be hit. PCB Design Requirements for COB 1. The finished surface treatment of the PCB board must be gold electroplating or ENIG, a...
