Fuji is the best, but there are other alternatives besides Quad. If you really want to look at Fuji, take a peek at their XP142E series. With "Vision processing on the fly" and a "Mini Turret Head" with 12 placement nozzles it should fit your needs n

I forgot to add that we are using a 3 mil stencil. It seems like to me that may be there isn't enough flux left when we reach liquidous?? About half of the solder spheres do melt and wet on each pad, but the top half of each solder joint is just the

Hi Clarissa, seems to be a real start up situation you are in. For the printing there is IMO no need to buy any sophisticated automatic-vision-alignment-self-cleaning-inline-and-more-machine. Features you need: - adjustable in X-,Y-,Z-axis (individu

I've never seen a good article with a definitive explanation - just speculation that the increased wetting forces due to nitrogen result in increased tombstones. My own experience is that nitrogen is a very minor contributor to tombstones and can pr

Hi Experts, I am interested in having a tool or process to measure coplanarity between the PCB pushed-up in the printing process and the Stencil. Therefore having a way to calibrate them.

As the article eludes to, you still need probe access to measure the pins with TestJet. One thing I wanted to add was the use of JTAG for use with Boundary Scan. Certain devices have JTAG capability, but not all JTAG devices are Boundary Scan compa

$100K for this entire line. We are thinking of getting a Chinese made reflow oven that looks pretty good at $25K. Also, we need to deposit solder using a dispenser as stencil printing will be reserved only for higher volume boards. It will not be pra

you are seeing a typical issue that is caused when such small volumes of paste are printed....there are several reasons for it..the tiny amount of flux in the small deposit becomes exhausted much quicker then it does in a larger deposit ( the flux ma

There's normally a number of reasons people want to know what melts 1st, 1 - to see if you know, 2 voiding issues - whole can of worms 3 device alignment. One of our collegues has said that most balls are Eutectic, that's in fact not totally correct.
