hello guys ; we are using some standard selective wave soldering unit used in lined ; the drawback of a such machine is 1/the speed which is quiet low (the board is coming on position through the conveyor, then the head delivering the solder moves s

Although I am certainly no expert here I have seen a very fine looking piece of machinery for selective soldering. Although it too has a small fountain it is fully programmable and relatively fast. It is the Seho MWM3250. Check it out, it will be wor

Pascal: Two things: 1 Selective soldering machine discussions and supplier lists are in the SMTnet archives. 2 Some people consider selective soldering machines to be very specialized use tools (too selective ha ha ha) and think carriers tooled f

Durastone pallets, we use lots of precision ones for selective wave soldering. An utter nightmare to machine - hideously fibrous. We use http://www.globaldatum.com/ for ours.

You will need to preheat the boards for a lead free selective solder process. A preheat module is critical for any wave or selective solder process, if you don't get the board preheated properly the solder is going to resist flowing to the top of the

Hello experts, Here is my problem: I have a board that has smt parts on one side and TH parts on the other. We designed special pallet for wave, but the pallet itself is 15mm thick, so we are still seeing some defects. Have any of you tried to find
