Has anyone had trouble with SMD machine placing of SC-79 (approx 0402) varicaps (infineon, alpha, philips)? Using the recommended pads from Infineon I am struggling to get the component to place flat on the PCB and the pins to wet properly every time

During BGA rework we are asked to protect adjacent compoennt from secondary and/or partial reflow. That is our normal process. However, the customer is asking that the peak temp of the joint at the adjacent component should not exceed 160C. Can you p

The first thing to do, as always with any trouble shooting, is to try to isolate your problem area, then it is much easier to pinpoint and find a solution for the problem. Some simple checks you can do, besides the good suggestions you got from some

Another this to check is the feeder itself and packaging. The feeders have a little shutter covering the part when the feeder advances. We have noticed a static charge build up in that, or the parts, causing the part to pull out of the pocket when

Hi has anyone noticed any issues with reduced component lead diameters on through hole resistors? All the volume manufacturers have or are in the process of reducing the lead diameters from 0.6mm to 0.4mm due to the huge increase in copper prices o

Questions are: * What is your concern about this capacitor? * Are you running a leadfree process? * Is the component leadfree? Generally, we are ecstatic when compoents are on tape and not in plastic bags. And if they solder, well, we're dancing in

We're not sure what you mean by temperature sensitive components. From an assembly process stand-point, every component we use is temperature sensitive to one level or another. More specifically, some of our products use polyphenylene sulfide (PPS)

Hello, We are currently trying to design and ultimately implement a system that will be able to count and manage component placement for three Sanyo chipshooters on three SMT lines. As the number of components decreases in the reels we want to be ab
