Lead (SnPb) Finish for COTS Parts

Maxim offers two lead-finish (SnPb) options to mil/aero customers who require lead-finished products instead of the standard RoHS-compliant (lead-free) COTS parts. These special programs, one for low volumes and another for high volumes, apply to virtually any Maxim COTS plastic part.

Low-Volume Lead-Finish Program

This program works as follows:
  • Only a low minimum order quantity (MOQ) is required (50 parts)
  • Matte tin (Sn) finished COTS parts are taken from lead-free inventory and refinished with a 63/37 SnPb hot-solder dip
  • These lead-refinished products are marked with orange epoxy dot per GEIA-STD-0006
  • All parts are fully tested using the original QCI test program
  • XRF data is available upon request (shows that the original matte tin finish is gone and thus can no longer create tin whiskers)
  • Maxim warranty applies
  • Part number suffix: /GG8

High-Volume Lead-Finish Program

This program works as follows:
  • MOQ is a function of the number of die on a wafer
  • Product wafers from wafer inventory are processed on the original lead flow using 85/15 SnPb electroplate
  • Part is marked as the original leaded part (no orange dot and no "+" mark)
  • Parts are fully tested using the original QCI test program
  • Maxim warranty applies
  • Part number suffix: /GH9
