At this point all the sensors, switches and solenoid valves were checked. Their electrical signals and actions were phisically checked at the I/O cards level (Panadac 783-065 and 065A). Above mentioned signals were monitored from "I/O Monitor" functi

Well, for some reason the board house will pay for the boards but has some issue with paying for the parts on them. Why am I not supprised? Perhaps I have mis-diagnosed the problem. We have found two different board p/n's with the same type of defec

For this general question, not a consistent bridge but instead more a question if you had a component that randomly had a bridge, to avoid unneeded rework could you accept it as long as electrical they're common? But I think as you have mentioned, r

Ted Dangelmayer's book [ESD Program Management: A Realistic Approach to Continuous Measurable Improvement in Static Control; Dangelmayer, T; Kluwer Academic Pub 1999 e2; 0412136716] is excellent. Often, ESD supplies sales-types use the "Chicken Littl

Yes to be quite frank and stright foward your trash cans and bags do affect ESD. Esd also tends to jump thereore you do not actually have to touch the parts to create electrial overstress to the parts. As was mentioned in a previous posting there a

Hi Etimov, Understood that to us assembling parts that IPC is king, however it isn't neccesarily the bible for design engineers. We've had customers demand almost zero voiding, or had to use conductive epoxy to avoid it. For some of us solder joi

CK, If the contact length with the wave is decreasing when decreasing the conveyer speed and visa versa you need to check the machines electrical or electronics something is very wrong. Contact length is determent by wave design, wave height, convey
