Efren, Most of the previous posts offer valuable information. Certainly you should consider panelization of the individual circuits. Otherwise you'll waste valuable production time passing 3" boards along the line. Your orig estimate of min thruput

I have used, Siemens, Juki, Fuji, Universal, and Assembleon. All of them can do the job, depending on the machine mix selected. I personally prefer MPM screenprinters, after using both DEK and MPM. BTU, Vitronics, Heller, and Ellectrovert all make

I'm in the middle of developing an ESD program at my company, trying to adhere to S20.20 as much as possible (and the suggestions of the ESD audit conducted before I got here). I've been discussing the pros/cons of pink-poly foams and black foams.

This type of component packages works best with vision type: 254 - irregular. Measure the total package length including the leads. Also set the body dimension x-y tolerances to at least 0.35mm and the the pick up x-y tolerences to 0.5mm in the part

While the 85% yield on a per board basis seems low, we are actually running over 99% yield on a per solder joint basis as there are about 17,700 joints per panel. On average, 9 out of 63 boards in the panel need rework. Rework issues include missin
