Hi It's me again. Our products need to pass a chamber test 45c/36hrs after the PCBA completed batch of functional tests and assemble in to case. We found 1 unit was functioning for 24hours in the chamber, but hang after that. We tried to re-boot the

Hello Spoilt... Yes it's true about the kitting being important but we also offer a component tester/verifier option for our system. The components can be tested for each insertion if you wish. The machine will not allow a component to be inserted

OK I know it is funny to have two different PWB/PCB processes, one for pre production and one post production yet it is possible if controlled and implemented in a strategy. In debug if your company's experience has been for a repeated need to do IC

Sure, researchers measure shear as an element of their material characterization process, but that does not make it an acceptance test. [Truly, this conversation is not uncommon on SMTnet. So, it would not surprise me if an enterprising something o

Mentor Graphics - vPlan with optional CAMCAD DFT tools might have something....chat to Mentor on this.. CAMCAD supports DFT Functions and exports to Takaya I think

Hi, I need support on the method or applicable standard to measure the shear force strength on chip capacitors and resistors. I know the soldered joints strength is related to land desing, solder volume, pcb and component solderability, component

There is no test. Beyond the issues that you mentioned that affect shear, an article published in a recent [1/01] "Journal Of Surface Mount Technology" documents that shear is also dependent on the rate of shear. You may be able to contact the auth

The main function of the test is to evaluate the solder mask. Basically you are testing three samples: #1 - No solder mask, #2 - solder mask without solder, and #3 solder mask with solder. The solder pot is used to apply solder to the patterns on O
