Manncorp makes a motorized version which we use, I believe the model is Toppoint. Has never had an issue, not sure if the price is competitive, but works well.

Thomas: Wheeee, a 40% failure rate. Now, that make your boss chase you around the room won�t it? As you indicated, x-ray won�t do dip about helping to identifying problems [or ball cracks either]. Consider using an ERSA scope [er whatever they ca

I would like to bring a Vtek Versacount II SMD counter on line but it is missing the tape guide. Can anyone give me some dimensions so I can have a new one fabricated. VTEK has been no help at all. I am mostly interested in the tape guide groove. I n

Hi mates, was going thru the IPC-A-610C Standards, and noted BGA voids stands somewhere between 10%-25% voids permissible in the solder "ball" bump, after reflow process. Was wondering, hypothetical case study, is there any specification for voids

Hi Efren Unfortunately I cannot say about prices, because I don't know them in your region. But I can offer you to consider the world-leader manufacturers of each type of equipment. I think you can obtain all information through their web-sites. We s

Hi Raeto, 1. You do not have reflow oven. This means that you are not running Surface Mount Technology in your shop floor...am I correct? Why do you plan to have SMD's under your PCB's ? Can't you replace them with their PTH counter part and have th

| | Our spec on voids is 30% ball diameter in the center. On the component to ball and pad to ball interface, we use 25%. To determine this spec, we asked around. I don't know of any studies that have been done to verify if this is OK | | | | Regard
