Jumper wire hold down

I can remember seeing jumper wire that had special insulation that you melt to the board to hold it down instead of gluing. Does anyone use this product and can tell me where to get it.

Melfs drops down from nozzle

Electronics Forum | Mon Sep 11 08:22:56 EDT 2023 | richardcargill

A lot of MELF components have solder ends that stand slightly proud of the main body where your vacuum would lift them, so vacuum leaks are most likely the culprit. Upping the Vacuum to the nozzle may help, but better thing would be to modify the noz

Laying down and holding large components

Electronics Forum | Thu May 22 13:31:52 EDT 2003 | Dave

If you have a component with a height issue and want to lay is down (capacitor in this case), what are the best methods to consider? RTV, epoxy or something else?

I would assume we are talking about a radial leaded electrolytic cap? We use Electronic grade RTV (Dow corning 3145). It sticks good and can be removed if necessary. It is also pliable so you don't have to worry about CTE or other stresses that may

We need more information to give you a good answer. Is this a leaded part (axial or radial) or smt? How big is the part, how much weight per lead? What is the end use environment, will it see any vibration? or temperature extremes? Some general com

Would you consider a light reflow pallet on second side holding the connetors in place and preventing them from moving?

OK, you can't glue, Pallet Guys pallets are out the door, dual line reflow prevents from any lower temp solder paste.... Do you have a 3D printer? Are there parts underneath the connector in question? Measure the PCB thickness, pint out a custom hold

How to install FBGA ICs on both sides of Flex boards with no stiffeners ?

Electronics Forum | Thu Aug 09 14:00:51 EDT 2018 | tey422

To me the most challenge would be the printing step. If you can print it, you should able to run it with SMT. We ran similar thickness flex boards before. But it's long flex with small stiffener at both ends, and it was 10up array. You need fixture
