The PCB Manufacturing
We use the data (Gerber file) that you send us to create the production information for your customized boards. Our experts match your specifications with the capacities for compliance purposes.
We apply an oxide layer to the inner board layers and then stack them together using prepreg to create insulation between them. Additionally, we should add copper foil to the upper and lower stack parts.
This is the second electrolytic plating process, where we carry out extra plating in dry film parts (circuitry). After depositing the copper, we should apply tin to prevent the plated copper from oxidation.
We will test all the boards before shipping to ensure all of the printed circuit boards are free of defects and meet the standards you expect. Currently, we have two different types of testing equipment available to test the circuit boards. Some test machines include a flying probe, fixtureless testers. And we also have universal grid testing capability. These machines use fixtures built specifically for your PCB. If you have impedance control requirements, we will also test the impedance value of the coupon.
Since 2007, WellPCB has offered good-quality PCBs with excellent turnaround time and customer satisfaction. We are one of the biggest and most skilled board manufacturers in China. Our committed staff- with a rich experience in the electronic world- produce superior products, such as double-sided, single-sided, multilayer, and HDI PCBs.
PCB Factory Scale
We handle all production scales, including small, medium, and mass production orders.
Besides, we can deliver more than 10,000 products monthly.
We have competitive prices and unbeatable offers for volumes ranging from as small as 1 square meter for you.
Here are the certificates we have:
IATF 16949:2016 ISO 9001:2015 ISO14001:2015 ISO13485:2016 UL Also, all our products follow the IPC & ROHS Standards. More importantly, we always strive to manufacture high-end PCB products.
PCB Product Show
1. What services do you offer?
We offer three primary PCB assembly services: PCB fabrication, consigned PCB assembly, and full turnkey services.
2. Is it possible to get stack-up drawings from you?
Yes, we are willing and ready to share some of our standard stack-up drawings with you, or even individual stack-up drawings that meet your specific requirements.
3. Do you offer any discounts?
Our two factories offer price support for various orders, especially for multilayer PCBs and mass production.
4. Can you view and process Altium CAD data directly?
Unfortunately no. We generally deal with Gerber files.
5. What if I am dissatisfied with PCBs from WELLPCB.com?
If you encounter any problem with our products or feel dissatisfied with our products or services, you can let us know through [email protected]. We promise to get back to you within 24 hours and serve you satisfactorily. We will either refabricate your PCB in case of a defect or refund the full amount without needing to return the defective PCBs. You may also choose to credit your[email protected] account and use the credit for future orders.
