Electronic components are basic electronic element or electronic parts usually packaged in a discrete form with two or more connecting leads or metallic pads. Electronic Components are intended to be connected together, usually by soldering to a printed circuit board (PCB), to create an electronic circuit with a particular function.

Most of the capacitors & resistors supplier have implemented Leadfree finished on their components and like it or not, most of the PCBA house already using them in their process. I just got a notice from my component supplier telling me that they will start sending leadfree capacitors to us and I told them no problem as I see most of the time, temperature of these small caps and res always higher compare to those big components during reflow. Some of them can reach up to 235 - 250 Deg C.
Can someone tell me what is the problem I could potentially see, when running this using Sn63/Pb37 paste ? What is the different between reflowing NiPd plating versus Leadfree Sn/cu plating, be it wetting finished & reflow profile requirement ?
