Didn't feel comfortable counting 4 reels at once on the Scienscope, would rather 1 reel, 1 label for our processes. The Visiconsult looks good and has a fast cycle time, with one in one out. The main issue here is that due to the weakness of £GBP a

If a few extra seconds of cycle time won't hurt you, recommend putting at max (3.0 sec) it will cycle all the way over to the Board @ Left sensor before extending BS and reversing. Otherwise play with the timing and requirement may vary from product

The answer to this lies within the datasheets of the components on the board. Each component has its own specs as far as number of heat cycles, time at reflow, peak temperature, whether it can be washed, etc. You do not need to be as thorough on th

I'm talking about NPM-dx machines, In the interface, there is an option called "Recognize by Mount Angle." Does having this option turned off mean that the machine head places the component as it picks it up? For instance, if a component on the reel

Dave, Thanks for the interest. Basically, we looked at this project as a straight swap, i.e. printing the glue on the PCB using a Dek screen printer instead of our current method of dispensing glue using a Camalot dispensing machine. For the PCB we

Hi Ken First of all, I think you are right to point out that the uptime should be calculated on the SMD line bottleneck. But I have some comments to your posting in general: The SMD line bottleneck, you say, is always the palcement machine. This i

What is a typical time/temp baking cycle for an assembly prior to BGA rework? This bake is intended to prohibit PCB or nearby component damage as well as protect the component being removed for reball. A 24 hr bake at 125C would be great, but often

Thanks Alexei for your advice. I consider mainly high-volume production with tape/reel feeders for most components and tray for big ICs. My ultimate goal is a cost estimation of the production activities. So departing from a parts-list, I need to est

Just a note, on fixed galden machines yes the way they compensate for rise time is as the previous post suggested, change power and also stage the lowering of the PCB into the vapor cushion ie not the main one but further up in the tank. The disadvan

Yes, you need to use "dedicated feeders" and only make changes when you run out of a part. It may even be better if you could convince the stock room and keep stock for those parts right on your line. The environment has to be proper for that though,
