Use a type 5 solder for maximum paste release.

Steve, On 16mil pitch I would try 12mil diameter on 5mil stencil, unless the BGA ball size is something unexpectedly huge.

Is anyone out there using automatic despensing equipment rather than stencils for depositing paste on BGA patterns prior to placement/repair. What is minimum dot size that can be reliably applied. Pro's/con's?

Agree with Siverts. We do a build that has 0.3mm pad diamter BGA (0.8mm pitch - distance from pad center to pad center) and 0.5mm dia. BGA balls. Stencil specs. are: 5 mil. thickness, square BGA pad aps. (1:1, 0.3mm square aps), laser cut. Seems

Good afternoon, You should use overprint technique if you have any problems with paste volume (PIH technology and mixed designs, for instance). Otherwise, it is useless. Overprint has to be made in such way so that paste would have an ability to flo

| Hi Kelly, | A couple of questions first. what type of BGA are these components? CBGA, PBGA, TBGA, etc. What is your aperture diameter on your stencil and what stencil thickness are you using? I think I can be of more help once I know the answer

We have used the Stencilquik™ BGA Stencils from the same supplier to attach some LGA's for a prototype run. We were able to get a few different thicknesses to see which worked best. They worked very well for that limited application. We did not tr
