The open hardware manufacturing tour includes four factories, presenting two kinds of factories in South of China.

  • PCB Plant: provide clean and working PCB for us to make boards
  • Molding Factories: including injection molding, CNC & punching

How PCB is made

Here’s a common two-sided printed circuit board processing, it needs 16 steps for each batch of board for 12 hours at least. The factories is cut into two pieces: one is for extremely clean(dust-free) room.

Raw materials – copper are send into production line. There’s a hidden process which prepare the photo tools to make the film from the gerber files. Those panels will be exposed to ultraviolet light.

Unexpected Grove – BLE.

The next step is to drill and plating the holes for DIP.

Picture: adjust the knife of V-Cutting machine to fit a specific board.

A tip is to make a V-cutting board so you can take them down quickly.

After V-Cutting.

The following is to drill the PCB.

How Models are made

『五金』is a typical Chinese word presenting the five metal product(golden, silver, copper, iron and Sn with variety of machining process such as drilling & milling.
