Hi, My Bottomside component pads are 1:1 with my topside land sizes/dimensions. I have difficulties catching solders on my bottomside smd chips (SMB Diodes, 0805 RC Chips). What should the bottomside components for wave soldering be greater than my t

Hi everyone, I'm relatively new to SMT PCB design and am running into some frustration with the land pattern design of "standard" smt components in particular passive chip components. It seems each manufacturer (Yageo, Rohm, Panasonic) has their own
