I am looking for a No-clean or water soluble solder paste, Sn63/Pb37 alloy, 15 - 25 microns (T5). I need to print with a 4.8 mil stencil opening. Does anyone know where I can get 250 to 500 grams in one week or less?

I don't have any actual "hard" data to give on improvements but, I can share some experiences with you. What we noticed when we implemented the Rheo pump was: No more solder "skips" on our boards, Improved print quality on our BGA's & 16mil fine pitc

Timed an actual Change today. It took about 6 min to actually change the head and then about a 2 minutes to start printing again after installing the new stencil & loading the program for the next PCB. The whole thing including stencil swap out & pr
