I can tell you that I have been involved in new process chemical introductions for 40 years. I have seen a lot of claimes and this is one of the best inovations I have seen. If I was not convinced of this I would not be involved. As for process impr

The 2009M is a water based flux and requires more preheating compared to alcohol based fluxes. After checking real chunks advice you might check if you hear sizzling when the solder touches the board (indicator that the water is not eliminated by you

Hopefully not too late of a reply... We currently have both, the Ersa ETS 330 (running LEAD solder) and Seho GoWave 1030 (RoHS solder). Bought the Ersa used, and it seems like a strong built industrial high volume machine. We've needed to modify it a

I would use a foam fluxer since spraying rosin will make the stickiest nastiest mess you can imagine. 18 layer board huh? You will want convection preheat, both top and bottom preheaters, preheat tunnel of at least 4-5', a chip wave, laminar flow w

I tried MS2 for almost two weeks and I can see it works. MS2 is more a preventive tool rather than a solution to convert pour on top of the dross. Very important if you use this stuff is that you do the encapsulation of the wave, the bigger the surfa

Sounds like the problem is design realted - here's a cheesy trick if your product/process permits: (you know how I love my cheesey tricks!) Put an adhesive dot between the pins that are bridging. If you're gluing bottomside SMT components to the bo

Hello John, There are some coatings for aluminum to eliminate solder drag out. The do not work with all fluxes it is called hardcoat anodized it is black or geen in color. Unless you have faily high volumn the hard coat cost can be as high as titan

What you can do is perforate the board holding rim by drilling holes of 0.6mm (similar to via's). This will reduce the mass and heatsinking capacity, allow excess flux drainage and facilitate convection heat contacting the board through the holes. Th

I've been in shops with a flux containment pan under the wave fluxer. While I'd rather see excess flux in a containment pan than on the floor, but I'd prefer to see flux applied precisely to eliminate the need for either using a containment pan or cl
