What is PCB Trace Impedance and How to Calculate it?
PCB trace impedance is the sum of all the resistance and reactance components of an electrical signal path. An ideal transmission line must have a characteristic impedance that matches both the transmitter and receiver of the intended signal. If the characteristic impedance of the matched transmission line is faithfully maintained, then the full signal sent by the transmitter is seen by the receiver at the end of the trace.
PCB Layout Guidelines For SMT Assembly Process Limits
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.
Typical 4 layer PCB Stack-up Design Guidelines
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
How To Set-up Best Trace Corners in PCB Layout
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?
Temperature and Humidity, Harmful to PCB
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.
An Introduction to Flex Circuit Stiffeners
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.
PCB Trace Width VS Current Value Calculator
While you start a PCB design, a typical PCB trace calculator will help you to get the correct copper weight and circuit trace width upon on the basic current that the board run.
Flex Circuit Stiffeners Design Guidelines
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.
