| We are going to smt ic's on the component side of our pcb's. | The problem is we are going to have to do this by hand. | We have a hot air station and vac pencil, but How reliable is this process. | We've tried it on proto's and had some shorting p

Mornin! We just had vendor in here pitching a "low-temperature rework system" which was intriguing, but too expensive. He did get me to thinking though, beyond heating ceramic caps before hand-soldering them, it seems like it would be advantag

Hello all, Been doing some comparisons on joints made using the soldering iron versus reflowed solder paste (on a QFP package). The difference is quite significant: the joints made by the soldering iron are inconsistent and in many cases not filled

| On various PCB's after building processes,such as reflow, flowsolder and wash. The soldermask on the PCB's have become discoloured, like a 'marble' effect all along the solder side of the board, it is lighter in contrast than normal, although when

| Our vendor proposed to supply us with shields made out of Cold Rolled Steel (CRS) electroplated with Sn (50 - 150 minches). Should I be concerned with solderability or are there a better alternatives to tin finish? | No matter the base metal, elec

Hi Folks, Need to draw upon the vast expertise in this forum... Whenever you fill a new wave solder machine with fresh bar solder, it seems to produce more than the normal amount of dross for a few weeks. I always understood this to be the solder "c

| I have a component that is glue cured on the bottom of a pcb. The component is a 1206 size jumper. It is made up of iron/nickel alloy. The problem I am having is that the part will fall off the board during wave solder. Is the component not abl

Back in the days when pots, skillets, etc. were made of cast iron, vegetable oils were used to "season" the iron to prevent rusting and also from the food sticking to the pot during cooking. It would be reasonable to believe that you could use the sa
