There are two places where Laser Soldering is used for rework. One is the low volume, high mix environment where the board value is high. The other is the high volume (regardless of mix) facility where fast process time and quick set-up is required.

We set up and ran this process at Nepcon UK with some success but we used a UV adhesive less than 10sec cure so no heat. Push off force for the biggest parts was over 800 grams. We have had to modify the design rules a little to make it work but it

Hi Bob, I know that that conductive adhesives have been considered as a lead relacement in the past, but have been ruled out due to cost and other process issues (surface tension etc..) IBM has extensive development data on the topic and had come up

Charles was originally an engineer with Texas when I first met him. I took over running the first SMT course in the UK using his materials. I met him for the first time when I was a boy, the new kid on the block at the Nepcon West conference 12 year

Yes Siemens has a fixed tray feeder for matrix trays. If I remember correctly the tray will occupy 1/2 of the table.The feeder is a two part system 1) is the base 2) the the flat tray (just like what is used in the waffle pack changer). the flat tray

we met the same problem with audit, and i make a tooling log for each stencil and in tooling log , set up some criteria for checking such as tension , mechanical damage, printing result ect. The stencil will be checked periodicly by process engineer,

The size/type of screw and its preloaded torque are determined by the type and intensity of the load being applied to it. This should be known or estimated by the engineer that designed the product. Then they'll typicly apply a large safety factor

T.W.I.M.C. I am trying to located a copy, or at least the proper number, for the ISO standards on soldering, rework, and PCB wiring. I am about to start up a SMT solder rework class at work. I recall that when I worked for Solectron
