The Practical B-52 CRET test vehicle is divided into four primary segments: 1. the main SIR test board; 2. the Ion Chromatography (IC) test coupon; 3. the solder mask adhesion coupons; 4. the SIR mini-coupons. Additional technical information specifications and guidelines can be found on the Practical Components Web site at www.practicalcomponents.com. Practical Components provides the test vehicles, components, Gerber files, and Aegis Circuit CAM files. If the goal of testing is to perform an engineering evaluation of the manufacturing process, then stock IPC-B-52 boards can be used, but should be as representative as possible. If the goal of the testing is process qualification, per J-STD-001 or IEC 61189–5, then the test vehicles should be procured from the customer’s existing PCB vendor using the same material set as for manufactured hardware.
