We built tens of thousands of boards with transeivers on them with a no clean process.Never had any problems with the flux residue in relationship to board performance.

I'm not too experienced with this but what about an air-blast with an ionized air source such as an air knife above and below a conveyor to push most of the fluid off of the pcba then run through an oven just above vaporization temperature.

Is there a steadfast rule of thumb for a good solder joint on an Enig Gold board. I come across this number 217C when discussing BGA profiles. Is this a published number? I sure could use a reference. Anybody feedback is appreciated.

The steadfast rule of thumb is: In order to get reliable reflow, you need to be at or higher than [liquidus + 20�C] for about 5 to 10 seconds, rather than those old "60 seconds above 183�C" guideline. This provides for setting your peak based on the

Hello everyone out there in the SMT world. I have a dilema I'm currently running a board that has 3 csp's with a .75 mm. ball pitch and .3mm ball size. And 2 qfp's-160. The stencil is 4 mils thick and I'm using a 63/37 solder paste. My reflow prof

"OK. If the connection doesn't look like I expect it to look, how do I know that the metallurgy is correct?" Comments are: * There are no pictures that will get you though this. * You should expect that gold that is dissolved in Pb/Sn solder to make
