We've been soldering leadfree components for maybe 15 years. We'd be surprised not to be able to store components for at least a year, not that we purposely do that. Component fabricator process determine the maximum storage time for components. M

SCOTT- We do solderability testing for the electronics industry using a Multicore and Kester Wetting Balance testers. The standards we test to is IPC J-STD 002 for components and J-STD 003 for PCBs. There is also a system called SERA we co-developed

Thank you Dave, that is almost the asnswers we use to give to our Customers when auditing they ask for component shelf life. But as you can imagine, they whant to see a quick information right on the label (on Reels, on trays, etc) like: Use b

Solderability standards are: * IPC EIA J-STD-002B - Solderability Tests for Component Leads, Terminations, Lugs, Terminals and Wires * IPC EIA J-STD-003A - Solderability Tests for Printed Boards Not intending to insult you, but terms used to descr

Dave Many thanks for your very informative piece on SMT.com As we stand we have not yet 'seen' any problem. My issue is that we have ordered (LTB) a very large quantity of ASICS and our usage has taken a down-turn. We therefore need to keep the one

Chris: I'm unsure about the kits you seek. Solderability of: * Components: J-STD-002, Dip And Look Method. Malcom Instruments makes a very nice tester. * Boards: IPC TM-650 2.4.12A Solderability, Edge Dip Method Good luck Dave F

Q1. What would you recommend for the best practice or comparison? A1. We'd go with dip & look. It's easy and cheap, requires no advanced degrees in measurology. Have you reviewed "J-STD-002B - Solderability Tests for Component Leads, Terminations, Lu

it has a lousy gage. * Solderability testing machines from different suppliers produce dissimilar results. * Tests don�t well represent in-use. For instance, how does one test the solderability of a BGA? [Ooo, ooo. I know the answer. => For BGA and

Nice to have you back on SMTnet. Some of the newer folk have missed-out on the solid contributions you�ve made to the Forum. The chicken wire cleaning basket was a classic!!! [It�s a shame that the folk at SMTnet can�t recover those files.] We bu
