Hi Bill, Thank you for your input. You've reassured me that I've made the right decision. As for Juki, the platform and footprint were not what I was looking for. Plus a demo I had with a Juki machine in the 90's went so wrong (it gave new definiti

Les, Some of the answers to design or stencil aperture/placement machine depend upon what is the current spacing between your components which you didn't specify. Chip components such as 0402's and 0201's typically have very small reductions in pas

What kind of oscillator are you placing (Manufacturer part #)? I do not believe that oscillators fall under the "chip component" category. Even if they did, most all SMT oscillators that I have come into contact with have 1 sided terminations on the

We are working to upgrade our BGA Rework Systems to place BGA's up to 150mm in size. We are encountering an issue that I wanted to pose to this group. When we get above 50mm in chip size, which is the field of view for the vision systems Prism, the

The QFP pitch is 0.5mm. Pad size is 1.475 x 0.3mm, and the new aperture size is 1.32 x 0.22mm. I'm not sure about whether or not it is lasered, but on the newly ordered stencil I selected the polishing option. Looks like the pad width is already 2/3

We have nozzles breakage troubleshooting since we uses the PANASONIC RMA nozzle on our MV2x Chip-shooter. Our nozzles are breaked in its opening, and cause components damages. Also, if anyone with experience in nozzles breakage with PANASONIC RMA No

I have a customer wanting to hide the identity of a particular component on a PCB assembly. The product cannot be potted and since the PCB is the product he doesn't want to pour over that one chip for aesthetics reasons. Any ideas on ways to permanen

When an assemblied board was on active service, what's the main reason for its failure:the package broken; the mechanics fatigue failure under thermal cycle; the corrosion caused by salt and vapor; the broken chip inside the package etc. I think all

We are looking for a source which can accept our packing material ( PVC tubings, Chip Trays, reels and spools , PCB waste rails from depanalization). Anybody, who is currently using a recycling manufacturer for these packing wastes. Our intent is:

Dear all, We haven't been using CPH (chips per hour) as an index of our production capability, but it seems more and more attractive as a basis by which we can compare the capability of different plants producing different products. Are there any o
