I'll throw my hat in the ring that says, "At least 95% of the pads must be properly wetted." BR, davef

This is a question about complying with J-STD-001 solderability testing. Do any of you have your vendors certify that the components and PCB's that you buy from them comply with the solderabilty requirements spelled out in the -002 and -003, in lieu

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

Are there any standard qualification/acceptance requirements for immersion tin board finish? J-STD-003 calls out temp/humidity preconditioning followed by solderability testing which is similar to what we have in our (ancient) internal documents. O

Larry, Our specification is 0.075% for our Fuji CP3 and IP2 machines. At or above that figure the Maintenance Dept. has to get to work. We typically see 0.03% to 0.05% on average. The Fuji machines are all vision centering. We have found feeders are

We test Parts and Components to IPC J-std-002/003. We also use a wetting Balance tester to determine solderability. We also test with SERA. We use ROSA to electrochemically revert the components back to their original state. Need more info ... email
