We have used a laser cut stencil 0.15mm (0.006") thick with 0.3mm (0.012") square apertures radiused in the corners 0.06mm (0.0025") to aid paste release. This approach with the (type 3) paste we use has proven successful on thousands of devices plac

Yes of course we are doing placement of BGA's with an IPII. However there is no front lighting so you can not inspect the balls. If the silhouette is square enough there is no problem with alignment. Just use the largest nozzle that will fit on the p

I am currently involved with designing a pcb which will use 225 pin bga,s The problem with this design is that the components will dissipate a lot of heat and the design we have come up with is use the middle 6 or 7 rows of balls as the grounding,th

I have been using an Air-Vac DRS-22 for almost two years with very good results. Once a profile is developed it is very repeatable. The DRS-22 is no longer available, however. It has been replaced by the DRS-24. Unfortunately, the DRS-24 has a lo

Hi, i have a confusion to read the dimension of BGA package from the datasheet. I have attached the datasheet below. Is this diameter of the ball 0.30mm or 0.15mm. I'm confused about the values given in the box. Whats meant by M, S, A and B. Please g
