YUNGUI 50X100mm PCB Boards,12Pcs Copper Stripboards Prototype Perfboard for DIY Soldering Electronic Projects

I live how these are patterned out like a breadboard! Great addition to my Electronics Laboratory Bench!

These are exactly what I hoped they would be. The overall quality is fine for a phenolic PCB. The holes are drilled not punched, the traces are well formed but unplated. Unplated traces means it is super easy to cut and remove the foil with a hobby knife. The foil is very thin. Do not overheat and use only a temperature controlled soldering iron or you will have problems like the one reviewer had. Some lead free solders may dissolve thin copper foils.Phenolic is cheaper than fiberglass and splinters if cut improperly so use a saw. This would be frustrating for anyone starting out so spend the money on nice fiberglass protoboards with plated through holes if this is your first protoboard.These are really useful for quick sensor or audio projects that use 0.1" center components. They make builds extra fast and easy. They are inexpensive enough that you can build projects and not worry about using up all your expensive protoboard.

These stand up to the heat of soldering ok. Would be much better if they were plated (solder, gold) even just a "flash" plating ... to keep the surface from opxidizing before use.

We used this board to create prototype circuitry to be connected to ESP32 development board. Many universal PCBs have either disconnected soldering potions or are arranged into connection strips that need to be cut. Some other boards mimic breadboard connections. The latter would be excellent except for the fact that ESP32 dev board is too wide to be used with breadboards and hence also with the PCBs that mimic them. This board is designed so that it can be used with the ESP32 when it is used off-center. So far this is the only such board I could find on Amazon.

I cut one of these up with a carbide-tipped chop saw. Expected it to break into flying pieces. It cut real clean. Then it soldered very well. Even soldered some SMT parts with paste and heat gun. All worked fine.

Using a good quality soldering iron and two to three seconds soldering time, 1/5 traces will lift.Using an expensive desoldering gun every trace will lift.This stuff is garbage

Most projects require integrated circuits and semiconductors, This board has proper hole spacings and I especially like the fact that it allows multiple (up to 4 solder) points for every IC lead connection. This is usually sufficient so one does need additional wire jumpers. Practical and affordable for experimenters and hobbyists.

I like the varied trace configurations. I expect to cut out desired segments of a board to use in lieu of a terminal block to ensure good connections and greatly minimize space requirements.Nicely packaged and VERY quick delivery.
