Downhole solder suggestions, in order of preference are: * Kester Sn96.3Ag3.7. Most vendors do not stock straight tin-silver alloys, whose wallet is that fat? * SAC305 can usually be used in place of one of the copper-free tin-silver alloys in downho

We are seeing un-Reflowed paste along the IC leads. There is only a very small amount imbedded in the flux, typically there is about 10 beads per lead. But on most leads. We are using no-clean Kester 256 paste (Easy Profile)We have not encountered th

Good one chunks!! Great way of proving a point With lead-free, engineers walk on thin ice and sales people are in heaven. If a flux can't handle an increase of 30C it wasn't a good flux to begin with.

true in the olden days, new osp's have excellent thermal stability. they are thinned or removed by organic acids mainly. contrary to believe due to the higher tin content they do tend to work well with lead free better than leaded used to. cheers gre

What is up with Indium 5.1 lately. Has Indium lost the recipe. The Lead free products from Indium used to kick ass, now they are biting mine. I'm looking at Aim 254 and Senju

I would be leary of a "Sucking" machine and hot liquid solder. Kester makes pellets that you put on top of the pot to seperate dross from lead. Technical Devices has a solder recovery machine Cal Agilent Technologies

Hi, I trialled 4 or 5 of the main suppliers including Kester. I went with Alpha OM338 SAC305 - exceeded all expectations and actually performs better than PB Paste in my opinion. aj...

It's possible that 90/10 is being replaced by LF in many ball suppliers' [Alpha Metals, Kester, AIM] inventories.

A no-clean paste with an above average amount of halides should do the trick. Kester EP256HA is a good choice for this application if you are using a leaded alloy (Sn63 or Sn62).
