For making electronic prototypes, I want to use both through-hole and SMT components on the same breadboard. For this, I designed a dedicated SMD perfboard since I couldn’t find any suitable perfboard on the market. The breadboard is a high quality, in contrast to many other breadboards. Because a lot of expensive working time is spent on a prototype, you don't want to save on quality.
These are the features of the SMD perfboard (front and backside are equal):
High quality gold plated perfboard
Square SMD pads breadboard 1/20”
High quality 1.27mm SMD breadboard
Perfboard for SMD and through hole
Example 1mm SOIC, 0402 and 0603
