In the world of electronic assembly and component/printed wiring board fabrication, there is no greater mandate than to develop lead-free technology. So it is with great anticipation that the new J-STD-002 Revision D, “Solderability Tests for Component Leads, Terminations, Lugs, Terminals and Wires,” is welcomed into the world! The new revision is a step forward in this regards and can be pre-ordered now from Document Center Inc. for expected delivery by the end of the year.
This standard prescribes test methods, defect definitions, acceptance criteria, and illustrations for assessing the solderability of electronic component leads, terminations, solid wires, stranded wires, lugs, and tabs. The document also includes a test method for the resistance to dissolution/dewetting of metallization. This standard is intended for use by both vendor and user.
The new revision is a joint publication of IPC, JEDEC, and ECA (soon to be the Electronic Components Industry Association (ECIA) with the meager of the Electronic Components Association (ECA) and the National Electronic Distributors Association (NEDA). Additionally, the joint committee worked with IEC to develop compatibility between the IEC 60068-2-20 Soldering specification and this new revision of J STD 002.
Significant testing has gone into the development of this new standard. Why? Because of the use of a new ROL0 type flux to replace the previous R type, which has proved inconsistant, providing false negative solderability test results.
This new standard activated flux composition, analyzed by NIST, Bill Russell, and Raytheon Systems, has proved to greatly reduce the amount of test variation, which is expected to reduce costs and improve consistency throughout industry. Not only that, but the committee checked in with flux suppliers to make sure that the new composition will be readily available!
