Designing and manufacturing your own printed circuit board (PCB) can be quite satisfying. Luckily it can be done cheaply these days. The list below has some of the cheapest manufacturing houses out there.
The cheapest PCB’s are small proto boards. You can order a batch of three to ten boards for around 6 US dollars. These companies often grab a bunch of designs from different customers and order them at once to cut costs.
Often restrictions on size, quantity, and the number of layers can apply. Furthermore, you must be patient because delivery times are between a few weeks up to months.
