Ok, that's small - I think you may need a special semi-conductor printer for this - positional accuracy on a "normal" SMT printer is no more than 20 micrometres from memory. In my semiconductror fab days we were printing with a positional accuracy

Joshua, 100um is 4mil aperture. You should ask several stencil houses about the possibility to print that small amount of paste(type 6 paste is available now with very small solder spheres 5-15um diameter). Even applying small amount(thin layer of f

Solder flux and solder paste deposition is a standard step during the chip attach and sphere attach portions of BGA and CSP assembly. A technique called ultra-violet fluorescence intensity mapping (UV FIM) has been introduced that allows flux measure

Mcmaster only had white in that style. I had no problem finding spatulas or putty knives that fit the function of what I was looking for, it was more of the color green for visuals. Its just a nice touch for the visual. I may just dip the handles to

It's hard to poka-yoke loading reels onto the machine (either a inserter-sequencer or a sequencer, then getting the sequenced reels properly indexed). The only way I know of to make sure they've been set up properly is with visual inspection of EVERY

We had a custom bar code storage and feeder setup. Stores material handlers would bring the parts to the line, scan the part number on the kanban card (always accompanied the parts), and the storage location LED flashed so they knew where the place

Hi, I purchase a leadfree aven solder pot 300w. We are wanting to pre tin power and ground wires prior to soldering onto pcb. I have some anti-erosion flux cored wire solder from koki S03x7Ca-70m 1.6mm. Can this solder be used? If not what is t

I assume you are saying that the rail width doesn't initialise when you initialise machine, but when you go into diagnostics and then exit diagnostics it initialises properly. (Not sure what cycling board on belts has to do with it). Have seen, on mu

I am wondering, I have an application for assembling a 0.4mm WLCSP to a pcb....the solder sphere size is 0.26mm...would you print paste in the normal printing process and then place the device and reflow...or would you use a fluxing station on the pi

I'm having some issues with lead time with my current fabricator of work board holders for my Universal THT machines (I won't name names). I've been waiting for a couple of months on some of my orders from them. My machines have a standard rotating t
