TK, Hope you got it right only for this round of assemblies. Well, passing through a Reflow belt is not an ultimate process to dry circuit cards & take out moisture from Solder finished layers. First of all, if the packs were not unsealed (even s

Any and all input will be greatly appreciated. So here it goes. I'm having an issue where the cad I'm getting from customers is referencing pin 1 as the parts placement. This isn't an issue for surface mount, however the aoi machine that we have in

assuming Sn05Pb93.5Ag1.5 Without knowing what you are trying to solder, PTH or SMT, the time might not be that far off. Does that time include stripping, cleaning, plating the leads prior to soldering onto the board?... pre-tinning the board as well

I worked for Electrovert for 20 years as a machine designer. Our first computer controlled solder machine the Century 2000 used Infra red pyrometers that were very accurate - once you calibrated it against what you wanted to measure. So the aim and s

Thanks for taking ur time to answer this. =) The pick and place machine is just pick from wafer(on tape) and place into waffle pack. I read from some of the sources saying that the ejecting needle and the vacuum pick up bits could cause the die to c

Hi all, We just got this machine and it is not fully functional. I read somewhere here that the folder mint has some useful stuff. I run mint and it said that it cannot communicate with card 0,1,2,3 (x1,x2,x3,x4). It said to make sure the cards are

We use both the blue static dissipative and black conductive ESD totes to store/transport our electronic assemblies. Our problem is that they get dusty/dirty and periodically need to be cleaned using ESD cleaner and a paper towel. Being that human na

Sn43/Pb43/Bi14 is a low temperature leaded alloy that has been used with very good success. The low melting point helps avoid some thermal shock issues on some assemblies. A word of caution, this alloy forms a low melting point at approximately 95*C.

Hi I do not work for a board house but a manufacturing facility where we do a considerable amount of soldering wires to through holes. We pretin our through holes on both sides of the PCB prior to reflowing the solder and installing the conductor (w
