Any experience of Winsource?  I've never used them but they claim to be 
able to supply parts we can't find.  Are they trustworthy?

Can you post a link: I found Win-Source, Win Source Electronics, Winsource and other similar names. MK

I ran across them while looking for unobtainium. They never actually found any parts for me. I also never found any parts from sources I could trust other than US brokers who took responsibility for testing. I just had one locate 900 parts in two batches. 400 were good, 500 had issues with solderability. Winsource seems to be a large company with a real presence. I have no idea if they can find your parts. If you'd like, I can give you contact info for the US brokers I'm using. If anyone else has US brokers with good contacts I'd be interested. I still need 1,600 units of a very hard to find part. -- Rick C. - Get 1,000 miles of free Supercharging - Tesla referral code - https://ts.la/richard11209

Thanks. I was asking for a client who's looking for generally less than 100 of any part. One of his engineers suggested Winsource and he asked me if I'd heard of them, which I hadn't, so I asked here. One problem is that these things are necessarily used beyond their published temperature ratings, and qualifying them takes a lot of time, so substitutions are difficult. He's decided to try Winsource out with an order for 40 chips. We'll see how it goes. -- Cheers Clive

I am guessing that the solder-ability problem was mainly due to oxides and sulfides. Are there any processes that can clean that up? -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Tangentially, one customer has taken to buying non ROHS parts because that's what he can get. He then uses the old technique of a series of lead-free solder baths to remove the lead. It doesn't take much lead to lower the melting point enough such that parts desolder themselves when used at high temperature. -- Cheers Clive

Wash with vinegar may work. Rinse well. SMD devices may need to be baked before wave soldering. Back in the days of glass Nixie tubes, I had the unsolderable leads problem on a weekend, for something needed on Monday. Solution was to dip the leads in dilute battery (sulfuric) acid, rinse well, and proceed to solder with ordinary 60-40 radio solder. Joe Gwinn
