BANNOCKBURN, IL – IPC released additional test coupons for the IPC-2221B Gerber Coupon Generator, an annual subscription service for IPC member companies.

The IPC-2221B Gerber Coupon Generator subscription service provides new industry-approved test coupons addressing blind, buried, stacked and staggered via structures. The tool is now updated with new features and coupons as requested by members, including updated “B” and “D” coupon designs that support not only through-hole but also stacked and staggered structures featuring blind and buried vias.

Designated sections of the “B” coupon for both registration and structural integrity evaluations are now included. The new “H” coupon design for evaluating surface insulation resistance (SIR) has been introduced, as well as the new “S” coupon design for evaluating through-hole solderability. Finally, the new “P” coupon design for evaluating the peel strength of outer layer metallic foils has been added.

Additional coupon designs for surface mount solderability testing, moisture and insulation resistance (MIR) testing of laminated base materials and solder mask adhesion testing are slated for release later this year and will be incorporated into the subscription service free of additional charge.

The IPC-2221B Gerber Coupon Generator subscription service uses an auto-quality check feature, ensuring the design rules for the test designs are met.
