7 Simple Steps to be a Printed Circuit Board Manufacturer This article attempts to illustrate how printed circuit board fabrication can be done easily at home. What are the simplest steps to follow if you want to be an at-home printed circuit board manufacturer?
The most basic requirement for printed circuit board fabrication is that of a PCB (Printed Circuit Board) layout program. This can be easily downloaded from the internet for free. Apart from the PCB layout program 6 layer HDI Rigid flex PCB, one will also require a set of specialized tools, which can be easily bought from the market.
The first step of printed circuit board fabrication involves the layout or the design. It requires the transfer of the reference schematic to the schematic capture part of the layout program. Wherever possible, you can choose to use the same designators as used in the reference schematic. This will enable you to refer back & make corrections later.
Step two is to use the PCB layout program to place the parts of the circuit on the board and route the copper traces. Initially, the board might look a little messy but as the process continues, this "mess" clears up & often, with luck, the PCB needs no external jumper wires.
Step three of printed circuit board fabrication takes place once the layout is over; the board layers are then printed with a laser printer on a special toner transfer paper. Then this board image is copied to the empty copper board with the help of a laminating machine.
As a printed circuit board manufacturer, your next step will involve removing the paper from the board by soaking it; this leaves only the toner behind.
Then the board is placed inside an etch tank, where the process can take anywhere between 10 and 30 minutes. Here, Ammonium Persulfate is circulated over the copper boards, while keeping the temperature of the solution at 110F.
Once the etching is done, a solvent is used to get rid of the toner and with the help of a soldering iron and a tinned solder wick, the board is tinned.
Finally mounting holes are drilled on to the board. And your printed circuit board is ready!
So, in 7 simple steps, you can be a home printed circuit board manufacturer.
