What is the maximum allowable thermal ramp rate for wave solder. We have a "short" machine used for selective soldering. To get the boards up to temp, we need to exceed our normal 2�C/sec. Are there any IPC documents governing this process? Anyone know of any components that could not exceed the 2�C/sec?
J-STD-001 - Requirements For Soldered Electrical & Electronis Assemblies is the governing document. It defines no specific limits like you mention. It states words to the effect that preheating should not do bad things.
