Q1. Is this a standard process for plugging? A1. Not as such. We checked both IPC-6012 and IPC-SM-840. Neither comments on plugging. So, your fabrication notes rule the day. Q2. Is this okay for such thick PCB's or is it mandatory to use a special pl

We are having issues with solder flooding some through hole pin receptacles which have an organic fiber plug on the soldering end. Anyone else use these types of receptacles and soldering with selective solder. Appears the plugs may be not sealed w

The blistering is around the plugging via. I can forward you the pic. For the plugging process, I'm not too sure how they plug. What is the correct practise for the plugging via. Now, what they did is. They will do a tenting process for both side.

First, plug all holes with nozzles or plugs. Then use I/O diagnostics to fire changer up and activate vacuum. Then try to remove each of the nozzles and see if the vacuumm holds. If it does, check vacuum detector switch (mounted on changer side). The

We have a customer that desires to have their via holes plugged with solder after assembly. Is it possible to add the via holes to the stencil and print paste into them and expect them to plug? If so, how much paste? One to one on the stencil opening

I'm looking for the pin out of the cable between monitor ( CRX 1500 F ) and the MCS-16. On the monitor side , it's a Centronic 36 pin plug. On the MSC side it's a standard DB 25 plug. Thanks for your time
