1. Most regular pcb design outsourcing companies charge according to the number of solder joints, generally 3-5 yuan/pin. This price provides invoices, contracts, confidentiality agreements, etc.

2. Generally, the charge for private work is about 2 RMB/ pin, which varies according to the different experiences of designers. For example, designers with more than 3 or 4 years' experience will not be charged less than those in 2 yuan, and novices will be charged less. Some can even be designed for you for free.

3. In 3.PCB production, different manufacturers charge different fees, and the fees of low-end and high-end manufacturers are also quite different.

Secondly, the design of printed circuit board is to realize the functions required by the circuit designer according to the schematic diagram of the circuit. The design of printed circuit board mainly refers to layout design, which needs to consider the layout of external connections. Optimal layout of internal electronic components. Optimal layout of metal wiring and vias. Electromagnetic protection. Heat dissipation and other factors. Excellent layout design can save production costs and achieve good circuit performance and heat dissipation performance. Simple layout design can be realized by hand, while complex layout design needs the help of computer aided design (CAD).
