Video to introduct what is IMC (Intermetallic Compounds)? how to judge IMC healthy?

There is a misunderstanding that people think the IMC layer grows the thicker the stronger soldering strength. The IMC layer can be grown and distributed evenly at the interface location will be good enough. Once the IMC layer grows too thick and ove

I have seen a similar problem once about 15 yrs ago. Someone decided to try a water wash flux for tinning wires. Bad idea! The wires were dipped in the flux, then in a solder pot. As the lead tin's it forces the flux in the strands to move up the wir

As mentioned the ProntoGERBER-CONNECTION software from Unisoft ( http://www.unisoft-cim.com/gerber_connection.htm) does the Gerber to intelligent shapes (ref des, x/y center, rotation, p/n, etc.) function for over 25 years. If you wish I'm availab

At my company we have to capture centroid data from gerber information on almost a daily basis, so tinkering and toying with quicker and easier methods of getting the job done are fairly common place with us. As stated by Richard Larue UniSofts cad

what software is out there that will extract XY centroid from gerber data?

Gerber in general is not best data set for assembly, alot of processing has to be done, manually or via software tools, all with their nice features, but as you state there is no actual datum XY , pin 1 , rotation references thus has to be 'generated

Yeh but, it's really terrible to conjugate and enter a killer topic and then have forgotten it by the time you need to re-enter it as the subject. Do they do it this way over on the Luke Warm Confusion Forums?

Well really the software supports the ability to have a topic that says one thing and a subject that says another. We actually didn't write this forum software but used a 3rd party product (that we heavily modified). They had this feature in there
