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!

In addition to the engineering fee, board fee and film fee, some special processes may have other expenses as follows
Additional charges are stated
1. Imposition fee: imposition means that different boards (if the same board is another one) are placed in a file. In that case, the imposition fee will be $50 for one model
Stamp holes, long slots, or direct milling open, are subject to imposition charges.
2 test fee: decide according to your actual situation (free test of sample during discount period);
3 taxes and fees: ordinary invoice taxes and fees are charged by 6 points of the invoice amount. Add a ticket is according to the bill amount of 12 points collection. The amount must be more than $3,000

7 board thickness engineering fee: it is the board thickness other than 0.6-1.6. It needs to increase the board thickness engineering fee by $100
Commitment to quality
All the boards used in sample making and mass production of shenzhensen yan PCB factory/PCB are international grade A materials, the quality is absolutely guaranteed, and if there are spare parts, also
Will test OK and give away for free! In case of return or exchange due to quality problems, the company shall bear the freight to and fro!
About the delivery date
