We are using Universal's Hsc for our production. the problem we are having is we are placing 0402 with a 8mm feeder with a pitch of 2, while running production, the feeder continues to advance with a pitch of 4. anyone have an idea as to why. the com

No max spacing spec. except that it should not be so far away from the other one that it is no longer on the board! IPC 782 shows .5mm spacing for the min.

| Most of the older placement machines might not have a 2mm advancing feeder. | Here is how I get by picking from a 8 mm feeder without loosing every second component. | 1. Define a second component in the BOM. | 2. Define this component in the feede

Hi, I need help to understand further on the via in pad for 0402 requirement. If I were to do the DFM over the brd design which consist of 0402 with via on pad, what is the criteria that I should look for ? I learned that the via in pad does not wor

Don't know if they "needed" embossed or not but....... I get an LED that is 0402 on embossed but, it is also at 4mm pitch as well.

I have seen 0402 inductors that look identical to 0402 caps, come in embossed reels, but the pitch on the tape was 4mm. Im not saying they dont exist, but i have never seen an 0402 component come in an embossed tape with a pitch of 2mm. everything i

Well, it took me a while but I had a look at some gerbers. On a PCB with neighboring 0402's 0.006" apart, and paste reduced 0.75mil on each side, I get lots of bridging. On a later rev of the same PCB, we have neighboring 0402's 0.018" apart,and pa

Hello all, Some background. We have JUKI machines (FX2, KE2000's and KE3000's) We're looking into an issue with 0402's in close proximity to each other. The paste gets mashed into the paste from adjacent parts. Some have suggested I deviate from

Hi, I am trying to reduce some 0402 cap tombstones. The main cause is the pad spacing is a little too far apart and the parts are as tall as they are wide .5mm I am stuck with the pad spacing for a while. All other parts are soldering well, even 0
