Professional PCB proofing circuit board and quotation reference

Huaqiang fast circuit board co., ltd. is a professional PCB proofing board manufacturer, which refers to the trial production of printed circuit board before mass production. It mainly applies to the process of electronic engineers conducting small batch trial production to the factory after the circuit design is completed and the PCB Layout is completed. In general, engineers call the PCB proofing before the product design has been confirmed and tested. Generally speaking, proofing means making samples. PCB proofing is to make a physical object of the designed PCB schematic diagram, which is a product test before mass production. A PCB project involves a lot of things. If a product goes wrong in one link, it will easily affect the progress of product development. The PCB board is also the same. Generally, the PCB designed for a project will go to the sample factory for sample making.

Test several boards. If the test passes, mass production can be carried out. The price will be much lower than the sample.

The company is dedicated to the production and manufacture of high precision single, double side and multi-layer circuit boards, and is a high-tech enterprise and research institute at home and abroad

Electronic product enterprise provides high quality product service.

We focus on customer value, focus on goals, work pragmatically, and keep innovating to build PCB with high quality, efficient and efficient delivery speed and perfect five-star after-sales service

The industry's most trusted brand suppliers.

Order need to know

When placing order, it is best to write your process requirements in the document. If not specified, we will follow the default process: FR-4, green oil white word, lead spray tin, through hole

Cover oil, 1.6 plate thickness of the process to do.  

Our company reviews the documents according to our board technology, the rules can be passed, then it will be done directly, can not help you deal with any data design problems, please be sure to review the funds

The material is under order. Due to the irreversibility of PCB production, orders for the same day will be arranged after 8pm, and the materials will not be modified after the arrangement of production.

As required by production management, the customer number or internal number will be added to all circuit boards. If not, please place your order. If not, acknowledge!

Please inform us to make the board after payment. Because there's a good chance you paid. We did not arrange the board. Also, send an email to

The client of mailbox also please note: please must write your want want name, mail is too much, we are very difficult to distinguish your mail!
