This is only the interest part of the sheet. There’s also a shipped/received list separate from it. You have been checked off the list already since you received them
2. Yeah. I’ve asked Digikey about this, and my Digikey rep specifically said:
Hi! Here is what I found:
1-reel(800pcs) w/bin code: F2T6Q2
4-reels(3200pcs) w/bin code: F2T4R2
5-reel and more(4000pcs+): Chromacity bin code can be specified to be manufactured at Samsung without guaranteed flux bin
So, it’s a bit problematic. The only way to get a good tint bin(T4, way below the BBL at 1A) is to order 3200pcs, and to get specific tint binning, it’s almost impossible.
The only ones we current have access to is the T6 tint bin. Good above 1A, not so good below that.
3. Have you tried using a temperature controlled hotplate? That’s how I do my reflows and component preheating. It works extremely well, and with my DIY stencil, it’s easy as pie.
- No, I don't have a temp controlled hotplate - might have to investigate getting one. I used the hot air from under the MCPCB, usually works. For driver/PCB reflows, I use a coffee mug warmer - works well, an EE friend actually gave it to me because he no longer uses it, but uses a temp controlled skillet or hotplate himself, mainly to handle bigger boards, etc.
For the coffer mug warmer, I turn it on and let it warm up a big, set the board on it and you can see the solder paste already melting, spreading, then use my hot air station at a more reasonable temp from the top while the board sits on the mug warmer.
Any recommendations and/or links appreciated for a hotplate - I'll search BLF now...
Hhhmm. Guess the 100x100 size would be good enough to do least a few 17 mm drivers at a time, and can handle the biggest drivers or MCPCB's. The shipping cost is big though. I like they can go up to 200C, better than 212F (100C) max of the burners.
