What is pcb test coupon
Test coupons. If you do decide to test with coupons, you'll need to ensure test coupon trace routing matches the board routing, including trace width and spacing rules, and should include ground traces. Generally, signal traces should be straight and openended with suitable signal and ground pads for probing (this will imply pads for everyHow can the answer be improved? what is pcb test coupon
The coupon is fabricated at the same time as the main PCB so the coupon will exhibit the same impedance as the PCB. The impedance of a trace is dependent upon all the PCB's dimensions and electrical properties so the use of coupons for testing is an accurate and reliable test for manufacturing quality and consistency.

The test coupon is separated from the PCB at final fabrication and is often not available when it is needed. (I usually get called in to troubleshoot the PCB after it has been assembled and the coupon is what is pcb test coupon Reliability Testing of Medical Electronic Circuits using IST Bill Birch President PWB Interconnect Solutions What is IST IST Interconnect Stress Testing Determines Overall Reliability of PCBs Powerful and Flexible Reliability Tool Objective Test Results Reproducible Test Results Automated Set It and For Get It Complies to IPC TM 650 A coupon or test coupon is a printed circuit board (PCB) used to test the quality of a printed wiring board (PWB) fabrication process. Test coupons are fabricated on the same panel as the PWBs, typically at the edges. Coupons are then inspected to ensure proper layer alignment, electrical connectivity, and cross sectioned to inspect internal The IPC2221B Gerber Coupon Generator subscription service is the only service providing new, industry approved test coupons.
