Additional Instructions

The specifications require that all supplied coupons contain adequate identification. As a minimum coupon markings shall reference the printed wiring board manufacturers’ CAGE (Commercial and Government Entity), lot or date code, and printed wiring board drawing number and serial number. Clearly identify what serial number boards are represented by the submitted coupons. NOTE: inadequate identification will result in the coupons being returned.

The coupons will be sectioned, poured in epoxy and ground and polished to observe various critical areas. One section from each coupon will undergo a thermal stress test by floating on top of a molten solder bath per the specification guidelines. The specification requires examination of a minimum of one coupon for every panel of multilayer boards produced.

An e-mailed summary of the coupon examination will be supplied to the requestor. The starting date for the coupon exam is the date upon which the coupons are received in the GSFC laboratory and a funded task is in place. Following the e-mailed report, a written report of the findings will be sent upon request. This report will include images of the causes for rejection if any are found.
