Any reason you're doing a RSS profile rather than a RTS?

Hi Team, Main reason for HIP are; 1. Warpage in component or PCB : Verified the part and PCB 1.6 mm thickness no warpage found. 2. Hip was at different locations : center as well as corner : So not because of warpage of component. 3.Solder paste equ

If you swear in having consistent print, I bet you it is the part. Some of these BGAs probably have missing or inconsistent balls.

Does anyone have experience with HiP defects with DDR memory components that they would be willing to share? I am interested in SMT process corrective actions and repair processes. I can discuss this privately if needed.

HiP most of the time goes back to the component package itself. If they are on the periphery of the part, it is a result excessive of expansion and contraction from the temperature. If it is in the middle, other contributors come in place.

Hi Team, Please help in suggesting stencil aperture opening for the 0.4 mm pitch BGA. PAD Diameter is 0.24mm. we have 0201 components also in same board. We have HIP in this BGA. Solder paste : Alpha Om5300 ( PB+ solder paste ) type 4 We have tr

You may well find it is the powder used in the gloves. Distributors offer gloves without powder. Also beware of using hand products with Lanolin, Mineral oil, Rose Hip oil, etc around electronics assembly ... solderability issues may crop up and ta

At SMT assembly level, the main HiP mitigation actions to consider should be increasing the stencil thickness/aperture sizes (typically in the 4 corners where warpage is maximal) + possibly reducing the reflow peak temperature as probably indicated i

Hi Guys, I'd like to collect info regarding YAMAHA YV88 Mark2 and YV100 series. Are they of any good compare to Universal GSM1 or Panasert MPAV2 ? My new company's products have hips of fine pitch components (0.5mm) and we are planning to get new eq
