We have an opportunity to purchase a Yestech YTV-1000 AOI machine. I am looking for opinions on how well they work and how they compare to the newer Yestech B3 AOI systems. We are a high mix, low volume EMS company. We do not currently have any exp

Hello, As our company has begun doing an increase production of contract manufacturing I have seen more and more designs with the 0402 pad layouts that are smaller (.015 in width) than the component. Also there is only a .008 longer than the 0402 p

Make sure that both lead frames are contacting the PCB pads when the part is on the placement head. We had an SM xfrmer that we were handling with vacuum by a ferrite cap that was not glued on straight. The part would contact one set of pads and get

Have you had bad experiences? We have a paste checker on line, and all components are verified at receiving and again when loaded on the machines. The purpose of AOI ( for us anyway ) is to reduce the time spent after reflow visually checking the b

Hi Umar, I believe you either are over printing these pads or the alignment of board and stencil may be off. Check your print right after your screen printer to verify either. If you are not over printing and your paste alignment is spot on, then

You can calibrate it until you are purple in the face. Job to job and part to part they are just not consistent.They either fail parts or put them on skewed. I have gone back and fourth on this for(10+) years. We have had Fuji look at it and we have

Dhanish, on a CP6 if you have skew problems or missing parts begin by a center check on your smalls nozzles. If all nozzles goods, you will have to check the Z zero of the table, this is the pulse count of the z axis (table height) when the turret is
