Roller tinning machine

Electronics Forum | Sat Apr 04 19:17:23 EDT 2015 | sync40

Hello to everybody. Does someone have some experience or review in the past with roller tinning machines? I mean low cost machines with two rollers and a molten solder tank. The finished soldermasked PCB pass through the rollers (like a lamination)

TH lead tinning process and solderability

Electronics Forum | Wed Apr 06 08:27:12 EDT 2011 | kaschliman

Our two component suppliers use 99.5Sn/0.5Cu and 97Sn/3Ag solder (respectively) for tinning their leads. We use 98.9Sn/.66Cu/.33Ag solder in our wave solder machine. Is there any significant advantage to either tinning process regarding solderabili

Hi, I purchase a leadfree aven solder pot 300w. We are wanting to pre tin power and ground wires prior to soldering onto pcb. I have some anti-erosion flux cored wire solder from koki S03x7Ca-70m 1.6mm. Can this solder be used? If not what is t

I have never added anything but bar solder to a solder pot so I have no experience with adding flux cored wire, but I have to imagine that it would smoke like crazy and gum up the sides of your crucible before you ever touched a wire to it. We use

You'll want to chop your solder into "bite sized" pieces for your pot, by the way. A bolt cutter or a band saw are a couple of ways to do it without ruining other precision tools. It's up to you for the alloy you use, but there are several (some

If you add any "flux cored" wire solder to the pot make sure you have ventilation as the flux will burn off and smoke like crazy. This solder pot is like any used in a wave or selective solder, no flux. The flux is added to wire prior to di

Hi, 1. do not use flux-cored wire- the smell is bad and flux will evaporate anyway at the time of solder wire melting. 2. as suggested use solder bars, something like this: https://smtnet.com/company/index.cfm?fuseaction=view_company&company_id=39635

Propensity of Immersion Tin surface finish fo whiskers

We believe imm tin suppliers say that their product does not whiskey, oops whisker, because they use 'white tin' not the 'gray tin' that causes whiskers. But as soon as you alloy their tin with SAC or any other high tin content solder, all bets are

OK, I feel the need to jump in here. Bright Tin has the tendency to easily whisker, and is almost never used, except on some through-hole connectors, I believe. Matte Tin is much less susceptible to whiskering, although under the right stress cond
