The issue is surface tension around the connector. Your tip needs to have more surface tension than the pins of the connector as it forms a cluster when being soldered. When I used to solder superfine connectors with a metcal iron it had a horses hoa

We rarely do profiling so we don't need all the new fancy stuff. But when we do I get a piece of aluminum rod and an empty reel of parts (preferably a 12" reel) fasten the thermocouples and wrap the loose end around the reel. The larger reel gives

We often do double sided SMT assembly, never had issues with smaller components. However, we apply glue to heavier components like inductors, SD card sockets etc. For this purpose, we have a glue dispensing machine inline after the solder paste prin

The 4 places I've worked in SMT all had their own solutions for their own reason. I quit worrying about what worked best if what I had worked OK. I've only seen (or recognized, at least) tension issues on foils that had been saved well beyond a rea

Evtimov , i agree with Thomas.. you don't have to take your mesure in the middle of the stencil since the sheet of the stencil has the same thickness everywhere either in the corners or in the middle.. So you can ask from your stencil supplier to mak

Much has been said on this subject. Try a search of the archives for the terms "Phil Zarrow" and "surface tension". You'll likely find what you need.

I'm writing the procedure for buying off the stencil. Can someone help to guide me on the most effective way of doing this job. Other than tension, mylar matching, dimensional checks, what are things that I need to consider. Pls help & thank you in a

The major problems are poor layer to layer bond strength(due to surface tension of most fluoropolymers),and poor cold flow,or dimensional creep of these materials.Please also click on Chapter Author Konsowski,listed above.E-mail form will pop up when
