Mold injection is an essential process to the full electronics manufacturing and box-building assembly provider. WELLER is one stop solution provider to global
The PCB impedance test coupon is fabricated at the same time as the main printed circuit boards manufacturing process, so the test coupon will exhibit the same impedance as the PCB performance.
Printed circuit board or Printed wiring board is a core component in any electronics devices, such as FR4 PCB, Rogers PCB, High Tg PCB, impedance PCB...
When electronic engineers create printed circuit boards (PCBs), they tend to leave many copper-free areas on the board. They are probably not aware of the technicalities of the PCB production process. A high percentage of the copper-free area on the board can have a negative impact on the product and leave it susceptible to early damage.
The best optimized PCB layout work will improve the yield in PCB assembly process. The considerations on this article will provide the positive references to PCB layout engineer to generate an effective job.
Our standard 4L PCB stack-up design options are suitable for most electronics design with upon global considerations of durable reliability, operation performance, economic cost and more available to PCB manufacturing process
When an electronic device design finished it’s schematic drawing stage, next phase is to start PCB layout work. So, how to set-up the best track (routing) corners in PCB layout? Which is a better option, 45° corner or rounded corner? Can be layout as 90° corner?
The circuit board is core component of any electronic device, and once it is corroded by moisture or high temperature, it will rise some quality headaches after PCB assembly process, such as moisture, blister, or layers de-lamination.
