You'd still have to change all of the part library references, make up new ones for new parts, enter feeder sizes, etc. More trouble than it's worth, once you know how to use the software and prep your cad data to be compatible with it. There are lo

It all depends on the quantity and the type of product / quality requirements. Manual placement for 20 mil pitch is not _that_ hard. Another advantage of hand soldering is that you don't have to worry about the moisture level of the replacement par

Brick (if that is your real name), Placement machines use centroid data to place parts. Generally this is derived from the "copper" that is etched on the board. Thus why we use the fiducials for alaignment. During board manufacturing, holes are d

Similar to Jax's comment, concern yourself with the the activity level of the flux. A more active flux would be more aggressive in removing tarnish. Certainly, the choice depends on the type and amount of tarnish. Probably, you need to consider your

Is the nozzle used to pick the offending used to pick other parts in this program? Have had experience where the LED's inside the nozzle backlight have broken down causing Vision Processing errors. And worth making sure that the brushes on the head a

We have used camera's before, mounted in suspect areas of damage, and recorded a shifts worth of work. When we found a damaged part, we found out what time the damage was found, then looked around that time frame on the camera. It can be complicate

We have been running double sided surface mount pcb assembly for several years with no adhesive needed. We paste, place and reflow one side, then repeat the process for the other side. With Rs, Cs and small to medium ICs we have no problem with par

Thank you very much guys. I really appreciate all your inputs. We just have another customer asking us a possible 3-day turn around of their prodcut from PCB Fabrication, Parts Ordering and Manufacture of their boards...just thinking on how can we do

Can anyone help me determine the acceptability level for lead deformation (see attachment). The outer two leads on the left side were bent during the pick and place centering operation. I've looked in the IPC-A-610 book and could only find informa

I agree, I'd try placing them with the midas or z-fi head depending what you have. Try using the mechanical centering in the zero angle with a low strength to move it straight. You'll probably have better luck finding a tool that will work on the hea
