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 have been using a hot air knife on Electrovert equipment for a few years. It must be set up properly for a given machine, primarily the distance from the trailing edge of the wave. Sometimes the set up must be adjusted for the assembly being sol

Some RF components are made in copper in weird spiral and parallel strip-line shapes. I'd either: * Send the boards back to where ever you got them and tell that bird brain to use SM-782 pads and practices. ... OR * Get the bird brain that sent you

broad answer. There's tons of suppliers. Go to "Circuit Assembly" magazine web site and look-up flux suppliers in the "Buyers Guide." Broad line suppliers are Kester, Alpha ... They will make you answer: I'm joining bla, bla, bla metals, using b
