Several methods work well. 1. (Low Volume Method) Using an Xacto blade, scrape off the solder mask holding the blade flush being careful not to use the pointed part of the blade. 2. (High Volume Method)Tape off the area that you don't want the mas

At my last company, we installed in-line testers. They worked very well, but there were some issues to be addressed; 1 - Boards had to be cool enough to go through ICT or we had false failures. 2 - We used no-clean flux...enough said about that. 3

Does anyone know of effective pick and placement optimisation tools for the Yamaha YM84 (Phillips CSM84). We are small manufacturers that have 2 YM84 machines, 1 being a triple pick machine for placing jelly beans and the other for placing IC's. We a

Hi Mike: If you are only spending around $150K per year in assembly I would have to say totally understanding your business that you should continue to outsource this operation. The cost of the equipment will be almost double that and it will be li

Hi, Lots of good answers and I am sure questions in the above. I have too many questions to really know whether your idea is a good one, as it could be, or one that will cause you more problems. Based on the size of the PWB that you will buy and t

Hi, I have a problem I've never seen before so I hope someone here can help. A recent batch of PCBs arrived where the copper lands delaminate with a small pull. Normally you have to pull pretty hard and the whole land comes off the substrate. These

We are currently cleaning solder paste (TAMURA SQ-1030FP) from stencil using an ultrasonic stencil cleaner with solvent (HYSPER-Non CFC). The process cycle time is 30 sec. cleaning in 1st ultrasonic tank and another 30sec. cleaning in 2nd ultrasonic

Well John here is the situation: I need to place an infrared transistor (optical element) with a tolerance of +/-.003", this is not a problem. A lens is positioned over the optical element and snapped to the PCB via three holes that have a toleran
