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.
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.
Stiffeners is an extra special piece of material adhered to specific zone on flexible circuits, which provide necessary rigidizing and support to SMD components assembly on a flex PCB board.
Stiffeners is a typical necessity to a flex circuit board, the flex PCB with stiffeners designed can ensure a best PCB assembly quality. And it will also take extra reliability and durability to your final electronics products.
