I read your query and reccommend that you take a look at using Infra-red heating technology. I just joined PDR systems and feel that the PDR Technology is appropriate for what you are trying to accomplish. Hope this helps !!

WE have a problem of tomb stoning in our smd assemblies during curing process of the boards in our Infra Red Soldering bath. Would you like to give us solution how to resove this proble? Thankyou Regards

I think you are talking about Infra Red motion detectors.Most of them are 4.5V. You can use a voltage regulator 7805 IC(5VDC Output) after your 12 or 9VDC supply. In case your detector requires a different supply voltage simply choose a 78XX(XX=Volt

Does anybody have any experience or knowledge of processing PCB assemblies featuring pyroelectric sensor devices, the type used in Passive Infra-Red Sensor modules? Since these devices are, by definition, very sensitive to heat, how do you get round

For some as yet unkown reason, we have started to have some boards sag and go under the wave. The boards are surface mount top side and conventional components wave soldered. We have checked the wave hight and both the profiles on the wave solder and

I suggest that you look at a few things: 1) The SMD pads may be too small for the part. Try to conform with the IPC standards in pad design. 2) The parts may be misplaced during the placement process. Tweek the placement program and if that doesn'
