Buying PCB & PCBA from China: 8 Questions to Ask Yifang Before Your First Order

Choosing a PCB supplier overseas involves more than comparing prices. You may be working with a factory you have never visited, communicating across time zones and arranging international shipping.

Before placing your first order, you need clear answers: Is the factory real? What does the quotation include? How will your boards be tested? What happens if something goes wrong?

Shenzhen Yifang Electronics Co., Ltd. was established in 2005, according to our company materials, giving the business more than 20 years of history. Those materials also show FR-4 multilayer, aluminum-based and copper-based PCB products, together with inspection equipment. [1]

Here are eight questions to help you evaluate Yifang against your own project requirements.

1. How Can I Verify Your Factory Before Placing an Order?

A company introduction is a starting point. You should also understand where and how your order will be produced.

Ask us for our company profile and factory video. Compare the company name and address with the information on your quotation, and clarify the payment beneficiary before transferring funds.

For your particular project, ask which fabrication, assembly and testing processes will be performed at which facility, including any processes involving production partners.

If certification is part of your purchasing requirements, request the current certificate and check its company name, manufacturing site, scope and validity.

What this means for you: You can evaluate an identifiable supplier and production route before committing to an order.

2. How Do I Know You Can Manufacture My Particular Board?

Your supplier needs to demonstrate suitability for your design.

Yifang’s company materials include FR-4 multilayer boards, aluminum-based boards and copper-based boards. [1] However, a similar product photograph does not replace a review of your manufacturing requirements.

Send your fabrication files and highlight the specifications that matter most:

• Material and layer stack-up.

• Finished board thickness and copper requirements.

• Hole sizes and critical dimensions.

• Surface finish and special processes.

• Inspection and testing requirements.

Ask us to review difficult features and clarify any proposed changes before production.

What this means for you: Your decision can be based on your actual design, with important requirements recorded in writing.

3. Will There Be Additional Charges After I Accept the Quotation?

A useful quotation should make its scope clear.

For a PCB or PCBA order, confirm whether the price includes board manufacturing, components, assembly, engineering charges, stencils, test fixtures, programming, testing, packaging and freight.

Here is an illustrative comparison—not an actual Yifang quotation:

Although Offer A advertises the lower board price, its total is US$50 higher.

What this means for you: Compare the complete cost for the same specifications and scope. Ask Yifang for an itemized quotation with clear inclusions, exclusions, payment terms and validity.

4. How Can I Reduce the Risk of Counterfeit Components?

For PCBA orders, component sourcing is an essential part of supplier evaluation.

Texas Instruments recommends purchasing its semiconductor products directly from TI or through TI-authorized distributors. It warns that products purchased outside those channels may be counterfeit or unreliable. [2]

This guidance highlights the importance of checking the sourcing plan; it does not establish the origin of components in any particular order.

Provide exact manufacturer part numbers and tell us which parts require specific purchasing channels or traceability documentation. Discuss shortages and proposed alternatives before procurement.

What this means for you: You can define the component sourcing requirements and approval process before parts are purchased.

5. How Will I Know the Boards Have Been Properly Tested?

Start by agreeing on what “tested” means for your order.

Yifang’s company materials show AOI, X-ray and flying-probe testing equipment. [1] The appropriate inspection method and coverage depend on the product and agreed requirements.

Bare-board electrical testing checks connectivity against the design data, including open circuits and unintended shorts. [3] It does not prove that an assembled board performs its intended function.

If you need PCBA functional testing, define:

• Supply voltage and operating conditions.

• Firmware and programming requirements.

• Required cables, controllers or test fixtures.

• Functions to be checked.

• Measurable pass/fail limits.

Ask which checks cover every board, which use sampling and which records can be supplied.

What this means for you: You can assess quality against an agreed test plan instead of relying on a general statement that the boards have “passed testing.”

6. How Can I Follow My Order and Understand the Delivery Schedule?

Production time and shipping time should be discussed separately.

Before confirming a schedule, identify the conditions needed to start: file approval, engineering clarification, material availability, component procurement and any required sample approval.

For an assembled order, missing firmware or a test fixture may also affect completion.

Ask us to agree on relevant milestones:

1. Engineering and file approval.

2. Material and component procurement.

3. PCB fabrication.

4. Assembly, where applicable.

5. Inspection and testing.

6. Dispatch.

Also agree on how often progress will be reported and how schedule changes will be communicated.

What this means for you: You can plan around a schedule with clear dependencies, a dispatch target and separate shipping assumptions.

7. Can I Evaluate Samples Before Ordering in Volume?

A sample order gives you an opportunity to evaluate the board in your own product before making a larger commitment.

Define what you need to approve: dimensions, mechanical fit, electrical operation, component selection and product-specific performance.

After approval, keep the manufacturing file revision, BOM and test requirements clearly identified. If the design, material or components change, decide whether further approval is required.

What this means for you: Samples provide evidence for your purchasing decision, while documented approval helps establish the requirements for volume production.

Ask Yifang for a sample quotation and a clear route from sample evaluation to the production order.

8. What Happens If I Receive Defective Boards?

Discuss the process before placing the order.

Agree on the acceptance criteria, inspection period and information required to investigate a defect. Repair, replacement or credit arrangements—and responsibility for related freight—should be defined in the agreed order terms.

If a problem occurs, provide:

• Order reference and affected quantity.

• Board or batch identification, where available.

• Clear photographs or video.

• Test conditions and the observed failure.

• Relevant measurements.

Keep affected boards available for investigation where possible.

What this means for you: Both parties have a defined way to investigate and resolve a problem, rather than negotiating the entire process after it occurs.

Why Consider Yifang for Your Next PCB or PCBA Project?

Yifang’s company materials document a business established in 2005, multiple PCB product categories and inspection equipment. [1] We provide PCB manufacturing and PCBA services for customers evaluating both bare-board and assembled-board requirements.

The next step is to review those capabilities against your project: clarify the manufacturing files, compare the complete quotation, agree on testing and decide whether samples are needed.

Tell us what matters most to your first order—quality, component sourcing, delivery or total cost—and send your available files and target quantity.
