Hmmm... Why would you want to to this? I understand your concern, but why not let your stencil house manipulate your Gerber and send you a copy of it before they cut a stencil? Saves you time and money. Sit down with your stencil manufacturer and

Lets take it a step farther. What about letting them use tapes or CDs in those walkmans? Would you allow them on the factory floor? Any ESD issues with the plastic cases? If not, would you limit the amount of tapes or CDS they could have with them?

we have used board mask that we let dry. It's tricky to get it flat with no spikes, but after a few tries you'll get it. I like the guys recommendation to try paste and let it dry. we have that problem when the operators do not clean the stencil p

it'll be cheaper if you'll let your wave machine up all night and let it in its idle temp (supposed to be 200��C) simply because it will need less power from idle temp up to operational temp compared to from 0�C-operational temp. Temperature Sensors

Let�s say I want to increase the shear strength of a solder joint. Does a lot of solder around a joint create more strength? Why not just absolutely bury the component lead in solder. My initial thought is that it doesn�t increase strength, but I don

We have the same Asymtek machine, same Humiseal product, same bubbling issue on touch ups. Ive found that very light pressure and a thinner mixture usually yields good results for us. Generally I dip the brush in the mixture and let it drip near wher

Hi Armando, I think you have to buy a bigger reflow let say 7 zones to get the correct profile. The reason you are getting that problem is due to short profile time. What is the size of your board? What is the composition of your solder paste? Ple
