Assembl�on feeders

Electronics Forum | Tue Jun 13 14:12:30 EDT 2006 | adlsmt

You have already come up with what I consider the industry standard fix. Attach your weight to one of those heavy duty black paper clips and it is pretty easy to move it up as the tape runs onto the floor. I know of a lot of people doing this. Not aw

Good afternoon, 1. Use only melf nozzles (Type 76) 2. In case if your melfs are picked up one after another try to increase feed time in machine setup, this will add additional delay and will allow feeder to complete feed cycle 3. Use the strongest

"We certainly live in a better world now." Regarding lead-free solder I assume? If so, then............... Oh god....... Another one sucked into the EU black hole of ignorance. Sorry for the thread drift, couldn't help myself. Hope your parts do

Wire to board soldering

I, too, would bend it 90-degrees prior to assembly and I would also put on a little spring loaded, removable, heat sink on to the wire to stop the heat transfer up the wire. After the wire is soldered, then remove the heat sink. Try the one from Ra

Are you worried the terminations might b oxidized? Do a dip test. If you have a solder pot carefully dip one termination of the cap into the solder. And see how well it wets. If that test doesn't satify the powers that be, then you can design a more

Hi Russ, I answered with a concrete things. I didn't say "ASK YOUR MANIFACTURER" or "CALL THE TECHNICAL SUPPORT" as the other posts on the same thread. If some of the things I mentioned could help, if the problem is one of them you have the solution

Ag/Pd Component Finish

Electronics Forum | Thu Jun 29 04:07:25 EDT 2006 | slaine

Hi I manufacture a range of components with Ag,Pd,Pt terminatons. Has the solder wetted to the componet and is the termination still left on the component? I would expect the solder to remain on the pad though, if all your other devices on the pcb ar

Ag/Pd Component Finish

I have question,is this the only Ag/Pd component in your board? If yes then concentrate on this component, I would suggest evaluating other component of the same value with Tin terminations. If I am not mistaken Ag/Pd plated components termination

We had one mechanical engineer from a certain customer telling us we had to crop components leads so they didn't protrude through the board, as they could then come in contact with the case as the board was flush. Had I have known then what I know

I had one SMT process engineer using rubber bands to hold a connector on second side reflow. Even the operators told him he was nuts. The zero stick through on leaded devices has come up several times for me. We clip leads first and pin in paste t
