Test Coupons

There are 4 different sources for coupons for the HC and DELAM tester - generic coupon library, customized coupon library and standardized coupon library. When the product features differ from existing coupons, a new coupon can be requested.

Generic Coupon Library

Generic coupons enable the customer to use a single design for multiple applications. The copper weights and feature sizes can be altered within limits as defined in the coupon modification instructions. Click on one of the technology boxes to download.

Customized and Standardized Coupon Libraries

The IST coupon designs are either "customerized" or "standardized". The "custom"ized coupon size varies greatly and is typically made specifically to fit the available space on a panel. The newer "standard"ized coupons are either .7" x 4.5" (17.8mm x 114.3mm) or 1.1" x 4.5" (27.7mm x 114.3mm).
Refer to the Standardized Coupon feature document for details.

New Coupon Request

New coupons can be created if generic and existing coupons are not suitable for your product. Please refer to the Design Work Sheet Page for details.

Coupon Zip File

The coupon zip file contains a fabrication drawing (.pdf), README file, Gerber 274x files and drill files. Newer coupon zip files may also include an ODB++ file. Here is a sample zip file

Coupon Latest Rev Tool

IST coupons may be revised to improve the sensitivity, increase the resistance etc. Each coupon is revision controlled. The revision of a coupon is the last character in the coupon name (e.g. slx10245a is rev "a" of coupon slx10245). Rev B and C or the coupon would be called slx10245b or slex10245c etc. The Latest Rev Tool can be used to determine if a coupon is at the latest revision.
