If you are measuring the voltage for a presence test that is fine. But you can not tell you the color of the led and have confidence that the right part is installed. Led forward voltages vary a lot between parts and between mfgs also. http://www.

We agree with John. It's possible to clean under 1.27 and 1 mm BGA. These devices have a reasonable stand-off that allows cleaning of water soluable flux residues with modern cleaners. So, if you have process problems with low-res fluxes, what mak

Make sure the board is stopping at the center of the worknest or you will waste lots of time (you'll get software limit errors when you try to find fids.). If it's not in the center, you need to go in and reteach from scratch (doesn't take too long).

I know Juki has the headquarters in NC, but they have a support office in the Silicon Valley with spare parts. I know they go to the NW area quite often from that office. They offer their customers 7-day/24-hour free phone support (including holida

Now that is creative! I going to talk to my machinist. I need a bar of aluminum machined to accept 24 pigs (ass up of course). Then I need a "squeezing" mechanism to apply a proportional pressure to the pigs abdomen to make the "ass gel" support t

Our "mechanical engineering dominated" company is allowing the electrical group to purchase some software to produce machine wiring diagrams. The only stipulation is that it has to be low cost. Can anyone throw out any products? I'm not looking fo

Just an idea... Try investigating methods for storing large drawings. We have a hanging file cabinet for E size drawings. You apply a self adhesive strip of mylar to the end of the drawing that has four holes in it. The cabinet opens up and 2 sets

We have a cabinet that holds all of our stencils. It is a homemade cabinet made to fit stencils with about 12 drawers and each drawer holds about 10 stencils. Each drawer is labeled with the stencil# for each stencil. When a new stencil comes in we j

We have done the same using a Red Mask instead of Green. Its definitely a good idea. It makes it easier to distinguish lead-free from lead assemblies. However, unless you are totally lead-free or two processes are isolated, it will happen that you

Yes of course we are doing placement of BGA's with an IPII. However there is no front lighting so you can not inspect the balls. If the silhouette is square enough there is no problem with alignment. Just use the largest nozzle that will fit on the p
