I would like a nicely packaged set of assembly tools (green handles and pouch) for use with RoHS assemblies. I have Green mats, dedicated irons, but would like clearly identifiable tools to better segregate the process. Can any of you provide a Man

Does any one know of a supplier high temperature PCB ink that can safely used between pads on an SMT connector. The product ideally should be screened on and have resistant to short exposure to heat from a selective lazer. Must be non-conductive and

You mention moisture in the part as a cause of cracking during reflow. What does this type of crack look like? How was it determined that moisture was the culprit? The resonator is near the middle of the PCB, but is about 5mm from a large hole (abo

For very simple boards, 2 layers lightly populated with light thermal mass, we still use FR4. For most of our Pb-Free boards we use the higher Tg material with moisture-resistant packaging. We are a CM so we don't usually get to change many of the

Always base your decision based on the need, rather than mearly comparing the specificaiton. The specifications are only indicator and not true performance for a specific application. Mydata and their agilis are good for high mix medium volume produc

Henkel Loctite makes a hot melt just for this. Do a web search on Loctite Hot Melt and you can see for yourself. Material comes in a variety of ways - we use the 10 inch sticks and their glue guns specially made for the material. Works well, is fa

The hot melt is prob the only way to go for that size gap. If you could decrease that gap I would suggest using 3M Scotchweld DP100FR. Check it out. We use the duo pak cartridges and mix nozzles with the gun. Very simple use and works great in our ES
