Chanzon 34 Pcs Double Sided PCB Board Tinned Through Holes (5 Sizes 2X8 3X7 4X6 5X7 7x9) Prototype Kit FR4 Printed Universal Circuit Perfboard for DIY Soldering Project Compatible with Arduino Kits

Item arrived today. I like how each size is warped together so it's not a mess inside the bag. The four non-plated holes at the corners are great for M2 sized screws so it can easily be mounted where I need it to. The only downsides were that for the 3X7 panels the corner holes seem to be a bit offset and that on all panels it's hard to read the letters and numbers, but it's okay. Waiting now for a soldering iron so I can start to work with these and they saved me a lot of money that would otherwise go for buying costume made PCB, great for the prototype stage of my projects. EDIT: Designed and 3D printed stands for these boards, as it would be a nice addition to my workshop corner.

Strong, easy to cut, multiple sizes, good isolation between adjacent points, 2.54mm or 0.1” distance between points. In your proto jobs it would be a good idea to keep 2 points gap between components as any uncleared flux can reduce isolation between points. ChanZon, could you please make a gold plated proto board and with a board material repels soldering flux even more? :)

Great product! Met all expectations!

Entering the wonderful world of pedal building. Built kits, modded kits and wanted to design and build from scratch. This was the next step in the journey. They are a good product and a good value.

Used these boards for my small electronic projects. They work well, although I did have to enlarge a couple of the holes to add several components.

Used this value pack to make a resistor box for a tap shift on my hotrod. Easy to score to size and solder flowed very well from front to back. Would buy again for sure!

Highest quality. Designs are flawless and very useful. The skinny ones have 4 wiring attachment pads, but are side enough to drill if desired. The number of pads lend the boards as exceptional for I2C prototyping. All boards are easily cut to size desired. When cut in half, they have attachment pads on one end for each board. All boards have the pads. The boards are strong and appear to be FRx fiberglass.

Good quality, good price, great for prototypes or one time builds.

Chanzon is a trustable furnisher of electronics components

Its my first PCB build in my life ! I'm no little about the field . I had fun doing it and was a total success . JST 2.54 header plugs fit mint ! Nothing bad to say about this board kits !
