Hello, I've recently started to work with MPM AP25, I began doing maintenance to get to know the machine. But now I'm having some problems in the teaching process. You can see the problem in the photo. http://img59.imageshack.us/i/image194p.jpg/

Hi Julie, My opinion is that the top board would not pass IPC, solder mask encroachment on pads. Second board is what we call Orange peel,this can be caused two way's. 1) the solder mask was not tack dried enough prior to imaging which caused artwo

Best to use Tin treated with TinP Additive. This ensures the Tin is fluid enough to Dissolve any Leaded residues. Run the machine for one hour at 275C then take out wave former and as much of the workings of the pot as possible. Then start bailing ou

Our products are a mixed technology; with both surface mount components solder side and through-hole top side, in addition to massive heat sink assemblies. We have been using your SN100C solder in our wave solder process with Multicore MFR301 Flux si

Hello, I'm having problems with voiding on an assembly that has a GPS hybrid with balls much like a BGA. This is a RoHS assembly using no-clean solder (Kester EM907). The voids are at or above 25%. I use an 8 zone oven where I peak in zone 7 and

There are several things that can be done. Shortening the lead length should eliminate bridging between lead. We had done a project several years ago where the customer had shortened the leads to almost flush to the board, preventing any chance of

Hello Mark, The centroid data you are currently using to program the MV-2HTL may be used with either platform. However, the libraries cannot be shared due differences in camera resolution. The MV-2HTL will have a 1.3 megapixel camera versus the 2 m

Of the machines you have mentioned, the APE Bandit is your best bet. I had one of those in a previous employ and it was basically bulletproof, and simple enough to work on if things went wrong. Simple controllers and enough power to do the job at r
