About Us: Who Runs PCB Manufacturer in China

PCB Manufacturer in China is a website for engineers and buyers preparing PCB fabrication and assembly projects. It brings board selection, manufacturing requirements, assembly preparation and supplier-verification questions into one practical resource.

The contact for this website is Tina@4PCBA.com. Use this address for project questions, content corrections and requests for clarification about information published here.

What you can do here

Start with the manufacturing guide to choose a board construction and prepare fabrication files. Use the assembly guide to define component sourcing, placement data, variants and testing. The quote checklist helps you combine those decisions into an inquiry that can be reviewed consistently.

The site focuses on questions that affect a purchasing decision: which requirements must be stated, which assumptions should be confirmed, and which records are useful when an order arrives. It does not replace the engineering release, approved supplier documentation or the terms agreed for an individual order.

How to read the capability information

The capability tables describe a reference scope for manufacturing inquiries. They are not evidence of factory ownership by this website. A published limit needs to be checked against the proposed stack-up, materials, geometry and production quantity before it becomes an accepted requirement.

For an order, request the identity of the contracting entity and manufacturing site, the confirmed technical scope and any certification evidence your approval process needs. Factory relationships, responsibilities and commercial terms should be stated in the actual quotation and order documents.

Our approach to useful technical content

Published guidance separates reference facts from project decisions. Numerical capability information is linked to a source where practical. Prices, minimum order quantities and production schedules require a project quotation; the website does not calculate them from invented coefficients.

Certification and inspection guidance focuses on documents that a buyer can request and check. References to IPC, ISO or UL should be read in that context. Visit quality control and certifications for the distinction between acceptance criteria, management-system certification and product recognition.

Resources may be prepared with AI assistance and checked against primary technical documentation. Where a source is incomplete or conflicting, the published guidance uses a limited claim and identifies the requirement that needs project-specific confirmation. If you find an error, send the page address and supporting evidence to the contact above.

Start with your project requirements

Whether you are preparing an initial prototype or a repeat order, begin with the current design revision, quantity and delivery objective. Identify which requirements are fixed and which are open to an engineering recommendation. That makes it easier to resolve questions before an order is released.
