SCC3 has an operating temperature of 200C, as long as it is heat cured at 100C. https://www.electrolube.com/pdf/tds/044/DCA.pdf It's also a silicone so needs to be coated & cured away from anything you value. Otherwise there are plenty of PU's and

| I am looking to apply 10-15�m of a conductive material that will withstand 280�C. Our product consists of an alumina substrate sputtered with NiCr (2000�) and Copper (2000�) and 15-60 �m of electroplated copper (all metals patterned on the substra

Read IPC-7530 "Guidelines for Temperature Profiling for Mass Soldering Processes (Reflow & Wave)". There is no advantage in dropping off much faster than 4�C/sec. In fact, you risk fracturing your newly formed solder connections due to board warping

Hey Bud. Allow me to 'turn' your point about 'grain structure' just a bit. Fast cooling rates / coarse grain structures was a bit of red herring in the early 80's. Faster cooling DOES produce finer grained solder connections. Accelerated testing of

we are using alphametals no clean 95sn/5ag CL775 paste. After reflow there are solder balls on the board. mainly are around the cap. We are using a conceptronic concept 60 air. There are 4 zones with 8 chambers. We are not sure what the profile

I know this is not the correct forum to post chip "reworking" questions but you guys have been very helpful in the past. My question is this, when we rework BGA components most of the time the solder reflows at a normal temp and all is well. On occ

Hello all Our Omni 5 has given the 'Cooling module high temp' warning twice during the past month. I suspect that the blower motor is the culprit but have not been able to verify this because the oven has started up normally after acknowledging the

Hi, I don;t thing there is an overtemperrature sensor. Just the thermocpouple returns a higher temp(voltage) to the controller and your software goes to alarm, cooldown or what ever it does. Emil
