Hello All! I have a problem that hopefully someone out there might have some ideas. I have an assembly that upon the "dental pick test" the entire solder fillet is coming up with the lead and leaving what appears to be a bare pad. I believe that th

We're going to begin conformal coating a few of our assemblies as required by our customer. We're using Kester No clean paste and will use cotton gloves to keep the boards clean while handling. My question is: Do we need to clean the boards prior to

Hi! Has anyone out there ever tried to use a high-temp and a low-temp solder paste on a double-sided board without using an adhesive? (Populate the bottom side with the high temp paste, reflow, turn it over, then run the top side). I looked in the

High temp paste or not, I feel it's all up to the oven,and/or the stencil design. are there sufficient solder joints, before running the opposite side (are the apertures large enough to achieve a hardy fillet or to small, allowing enough paste to vis

Vickij, Why not try using regular temp. paste for both sides? Unless you have some real heavy parts on both sides, you can run a double-sided reflow process with most boards. I myself like to place R's and C's first (or bottom side) and then do an

I am electronic hobbyist, which has made a prototype for electronic lock. On showing this to a company they become greatly interested. All the Smt for the prototype were placed manually on the prototype. I would like to set up a line without any huma

Production of 50000, is this per year, per month, per week, what? As for your budget of 80000 Euro, that is no much to go on. For a basic SMT line, you need at least 1 paste printer, 1 placement machine and 1 reflow oven. If you have any through-hole

This BGA could have gone through the reflow cycle two times as we understand from the BGA manufacturer, during the BGA ball attachment process. (If any ball is found missing, they replace the missed ball manually after applying flux manually and refl

We were using a Glenbrook RTX then upgraded to a jewel box. We have been extremely pleased with both Glenbrook units.Glenbrook has great analytical BGA software.Glenbrook and ERSA have also teamed up to provide total inspection solution package. 973-
