I found the problem... the vx cable trunking was the wrong radius, so when the axis was moving at slower speeds to read pre stop position, the axis was not reading the platen correctly due to extra downward force.. Ive now replaced the trunking and

Depends on the manufacturer of the paste... Rosin-based-flux solder paste usually takes 12-24hr's to fully oxidize with open containers. Water-based flux usually is 3-12hr's, but some have a 24hr open container shelf life... However, uncertain unt

Good day, can i seek an advice regarding wave soldering. Will it be advisable to reload the board two times to improve its barrel fill volume? If yes, what is the maximum number of times we can repeat wave soldering on the same board. If no, what

Test results indicated that the life of lead-free solder at a 2512 chip resistor could be worse than of SnPb solder in the accelerated thermal cycling condition. [Development of Life Prediction Model for Lead-free Solder at Chip Resistor, Changwoon H

Wow. Never have, never would, but that doesn't mean it couldn't be done. Mostly it just seems impossible to design a carrier clip that could hold both well...more likely it would hold one well and the other poorly, or both poorly. Anyway, is there

I agree with Joris. But to add to his comment, the type of finish also has a direct affect to your wave solder process. Going from a gloss finish to a matte finish may help a lot. As for humidity affecting your wave - I doubt it. I use a water

The simple answer is probably a lot longer than it'll take for it to short circuit due to moisture of some sort bridging two conductors. I say moisture of some sort because it doesn't necessarily have to be liquid water. A slug will do nicely.

Everything for a lead free job is labeled with green lead free labels. This includes all processing documentation. When the kit is issued to production the production supervisor and SMT lead operator are reminded that the job is lead free. When th

To get you started you might want to look at http://en.wikipedia.org/wiki/RoHS I think it's as good a place as any to get started. It has the basics explained in a straightforward manner. At the bottom of the page are external links they probably
