AVX and a few other companies make these chip transient voltage suppressors (TVS) parts that are a real *PAIN* to use. According to AVX: "Due to the semiconducting nature of the doped Zinc Oxide (ZnO) ceramic material, SMT TransGuards are no

Some comments on the previous post: Be careful when looking at the proportion of SMT defects that are solder defects - you may very well find that only a small few of them originate at the screen printing step. As for specification limits for pas

Couple of points are: * You're technically correct that ball height has the potential to vary by 8 thou, but we never see that much variation. Ball heights within a lot of components vary just about nil. * When we place BGA, we smush them into the p

For process management with SPC of the stencil printing process with a fully automatic stencil printer, what process outpur parameter would you recommend for SPC? It appears to me that there are two options: A: to have a pn chart based upon the % of

The lead was inspected for coplanarity and it's within the specification it's designed for and doesn't show any variation in terms of height as compared to it's adjacent lead that has good wetting

Hello Mika, I just checked a windmill and a test nozzle we have on the bench. The useful travel of the nozzle before the risk of the crosspin getting stuck in the loading gate is 1.5mm, if it gets stuck it is the nozzle is 1.7 up. If the cross pin is

| Hi, | We are in the process of evaluate our solder paste,incoming inspection over the solder paste, stencil requirments: | | 1- Is anybody using/requiring 1000 Kcps or more on viscosity to your solder paste provider ? Why ?? | 2- Is anybody using
