I don't think I would reduce the heat at all if there is no vibration in your oven or on the chain you should have no problem with them falling off or moving but you sure don't want a cold solder joint you no the solder joints are so easy to see go

Socket in wave soldering

Your IPC-610 workmanship manual will have the answer for you (I don't have the latest at my fingertips). Depends on what class you are building too, 1, 2 or 3 and the application of this connector on the product- which you must determine.

I'm considering purchase of a couple of smaller McDry cabinets model MCU-301SE. Has anyone purchased these or other Totech products used? Have you been able to get support for consumables? Any info helpful. Thanks.

I have Siemens F4 and S20 machines. Does anyone know of a spare parts supplier for these machines besides Siemens? Thanks in advance for the replies.

I think Siemens uses a third party to supply spares for older equipment. Have you asked them if they do so. Also you can often find this older equipment for sale at inexpensive prices.

X-Ray Inspection

Greetings, Can you recommend an X-Ray inspection system and recommend which ones to stay away from. Our use is for inspection of BGAs after re-work and repair - very low volume. Thanks Sparky_
