ISO 13485 in PCB Assembly: What It Covers and How to Verify It

What an ISO 13485 certificate actually tells you about a PCB assembly supplier — what it covers, what it doesn't, whether it extends to cable assembly, and how to verify entity, site and scope.

ENIG vs HASL: Which PCB Surface Finish Should You Choose?PCB Basics

ENIG vs HASL: Which PCB Surface Finish Should You Choose?

HASL is cheap and solderable but uneven; ENIG is flat, fine-pitch-ready and shelf-stable at a higher price. How the two finishes differ and a decision framework that starts from your components.

SMT vs Through-Hole Assembly: What's the Difference?PCB Basics

SMT vs Through-Hole Assembly: What's the Difference?

SMT solders components onto surface pads; through-hole runs leads through drilled holes. What each is good at, why most boards use both, and what it means for cost and files.

FAQ

Frequently Asked Questions

What services does BELI Technologies offer?
BELI Technologies is a one-stop EMS provider in Shenzhen, China, offering PCB fabrication, PCB assembly (PCBA), component sourcing, wire harness assembly, and functional testing — from prototype to volume production.
Is there a minimum order quantity (MOQ)?
There is no MOQ for prototypes. We support everything from a single prototype to high-volume production on the same lines.
Where is BELI located, and do you serve overseas customers?
BELI is based in Shenzhen, Guangdong, China, and serves customers worldwide — primarily in the United States, European Union, United Kingdom, Israel, the Middle East, and Asia.
What certifications does BELI hold?
BELI’s manufacturing is certified to ISO 9001:2015, ISO 14001, and ISO 13485:2016, and our processes are RoHS- and REACH-compliant. Assembled boards are inspected to IPC-A-610J and wire harnesses to IPC/WHMA-A-620 Class 2 / Class 3. More on the company is on our about page.
What files do you need to quote a PCB or PCBA order?
For PCB fabrication we need Gerber (or ODB++) files. For assembly we also need your Bill of Materials (BOM) and pick-and-place (centroid) file — here is exactly what each file needs to contain. Send what you have and our team will advise on anything missing.
Do you offer turnkey assembly including component sourcing?
Yes. We offer turnkey assembly (we source all components) or consignment (you supply the parts), with full traceability either way — the cost guide compares who carries which risk under each model.
Can you build products that need CE, FCC, or UL compliance?
Yes — BELI manufactures to your specifications using RoHS- and REACH-compliant materials and processes under ISO 9001:2015 / ISO 13485:2016 quality systems, and provides the build records and component traceability that support your product-level CE, FCC, or UL certification (final certification is performed by accredited labs on your finished product).
How do you ship international orders, and how long does delivery take?
We ship worldwide from Shenzhen via express couriers such as DHL, FedEx, and UPS, or by air and sea freight for larger volumes. Express delivery to North America, Europe, and Israel typically takes 3–7 days depending on destination and customs.
What are BELI's payment methods and terms?
We accept T/T bank transfer, PayPal, major credit cards, and Western Union. Sample and small-value orders are prepaid in full — the fastest way to get a small run onto the line, with no credit paperwork. Larger production orders run on a 30% deposit with the 70% balance before shipment, and established repeat customers can move to net payment terms. Every quotation states its payment terms explicitly.
What warranty covers BELI-assembled boards?
Assembled boards carry a minimum 12-month workmanship warranty, and longer coverage can be agreed at quotation for specific product programmes. If a defect is traced to our manufacturing, we make it right at our cost: full rework or replacement, a refund, or — often the least disruptive option — you have the boards repaired locally and we cover the repair cost. Boards can also be returned to us for rework.
Which Incoterms do you quote under?
Most customers order under EXW or FOB Shenzhen, and we also quote DAP and DDP when you want us to carry the shipping and import steps — see how each term splits cost and risk. Tell us your preferred term with your RFQ and the quotation will be built around it.
