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)

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

is there a particular solder bar that I need look into? this is new to me so I have no idea where to start looking.

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

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

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

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

What do you mean the solder must "survive" 260C? What is your target temperature? Is it dictated by a component, the substrate or the solder alloy? Do you require a eutectic alloy? If not, the selection of alloys grows. (these are from memory...n

Electroplating [electrolytic] and dipping [HASL] are the two methods for applying solder coatings to features on boards. Disadvantages of electroplating lead / tin are: * "Weak knees" created at the edge of plated through holes. [I used to get weak k
