The Difference between PCB Back Drilling and Controlled Depth Drilling

PCB Back Drilling is one of the special controlled depth drilling (NPTH) in the loop of PCB manufacturing process. Normally, there will be various challenges in engineering and production when it comes to PCB design and printed circuit board manufacturing and one of them is how to ensure high performance of retaining signal integrity.

What is the PCB Impedance Control Test Coupons

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.

Potting Resins in PCB Electronic Assembly

Today the electronics industry is one of the most rapidly expanding industries in the world, with an almost unlimited range of applications. more and more printed circuit boards (PCBs) are found in many domestic, industrial, automotive and military devices and require protection from their environment.

Discussion about common 4 layers PCB stack-up

There are general discussions on the laminated structure of multi-layer printed circuit boards, and most PCB factories have relevant training about this knowledge, which have thoroughly and clearly explained various laminated stack-up’s structures and principles.

Typical 8 Layer PCB Stack-up Design Guidelines

Our standard 8L 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.

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.
