Expected pick and place precision for 0603 LEDs?

Electronics Forum | Wed Nov 13 16:48:19 EST 2013 | spoiltforchoice

I would expect any half decent machine to place 0603 parts slap bang on target to the typical defined accuracy for such parts on most machines of perhaps ~60 microns or better. Self correction during reflow is IMHO much less pronounced with lead-free

Hi Folks, I'm working on a LED display that is composed of multiple layers. What is interesting for the point of this discussion is the PCB layer and the light deflector layer on top of it. Please take a look at the related pictures at http://plus

This is the model we have. The x-ray parts counter is from Optical Control and is a model OC-SCAN CCX.3 A.

I mounted the parts on the buck-boost DCDC converter and measured the characteristics

I received a buck-boost DCDC board with an optical sensor from NextPCB, so I mounted the components and measured the efficiency. Table of contents Board received from NextPCB Solder paste printing Mounting of parts Reflow operation check Attaching

SOD323 and SC90 bounceing parts in final PNP stages.

What we have had recently is a lot of larger thin (32 thou) thickness boards that have had issues with SC90 diodes bouncing off the pads in the final PNP machine. Our setup, universal instruments GC120 or quad beam 30 spindle lightning heads. This m

We have fought with cut-tape way too much. It's always a bad idea. We've tried a couple methods/devices for manual splice with limited success. Before you look into this I would ask them if they could supply you cut tape qty's inslusive of fairly

Paul, All the machines yulisted are very god at placement. One thing to keep in mind is parts availability. Some of our jobs come from the customer in "kits". Not everyone supplies you with a full real of parts. Be sure that the machine you pick

We have the same problems with cut/tape parts. But, we specialize in short-run prototypes, so I don't have much of a choice but to deal with it, and find a way to make it as easy as possible. We just demo'd a splice tool from Sierra Electronics (ww

BGA rework and inspection

Hi Yannick. This is an issue that we are just recently getting into but here is some ifo that I have gathered so far. I have seen/ used 2 different rework machines. The one we have bought is a 'PACE TF2000' which was at the lower cost end of the mar

Yeh, that RIPPPPP sound that seperating velcro makes is a real hint isn't it. Use your field meter to confirm your suspicions. We cut the straps.
