In assembly the bare board is populated with electronic components, called a "printed circuit board assembly" (PCBA). In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB.

hi all,
i have purchased an used vapor phase and i can't make a constant profile.
the profiles depend on the time i wait between two batch... the only difference that i include is the chamber temperature
i don't understand why the chamber temperature is so important for the profile;i thought that is the vapor that make the profile...
any idea why is not stable?

I think you are a genuis. The idea in your post is quite helpful and lights me. I have been puzzled for a long time in my new project.
