| How do I mechanically/visually inspect BGA devices when they are soldered to a PCB for possible solder, or other, defects as a first step before part removal and further analysis? I have had board failures due to poor soldering--I think? I can pr

I'm with you dave...please provide specifics as to defect condition... Are you getting good wetting to both land and lead? Is there any repeatability to lead/location/device? Do you have paste inspection capabilites to verify deposition? Is it a Pala

Dear SMT-manufacturer, I would recommend to also have other device joints on board X-ray inspected to understand if void formations are seen across the board or confined only to one component. If seen across, your "Reflow Profile" could be the cause

Our experience has been that mechanical crack occur vertically through the chip. In other words perpendicular to the board surface. You can sometimes tell through close inspection that the crack may have propogated from a point that the nozzle may

What is your plan/budget for your reflow oven and paste printer? Those are equally important as a placement machine. Have you factored in other costs of in-house assembly such as inspection, moisture sensitive device storage, rework tools, cleaning p

We are using Gerber EZ Teach to inspect near 100% of some boards. Many component footprints seem to be assigned custom packages. These custom packages come up as "preview errors" during inspection. I have noticed when I manually move the camera to th

I have three questions on moisture sensitive devices: 1. What is general practice on incoming / receiving inspection of moisture sensitive devices- which boils down to mostly FPDs and BGAs ? Traditionally, FPD packs were opened only at time of use

I have had good experience with the 6500. We used it to inspect both SMD and TH devices. (presence, polarity, correct part) I would suggest you contact CR (now Phton Dynamics) for the latest software. It has some serious improvments over early rel
