5 Medical Electronics PCBA Suppliers in China

When a circuit board is to be used in medical equipment, the core question is no longer just whether it can be used or not. At this point, the reliability, traceability and regulatory compliance of the product are all mandatory requirements that must be met. Therefore, choosing a suitable Chinese PCBA supplier for medical PCB assembly is actually a strategic choice related to product safety and brand reputation, rather than simply comparing prices and placing orders.

There are many factories in China engaged in PCB assembly, but only a small proportion of them can stably undertake medical PCBA projects. What medical device companies need is a PCBA manufacturer that can meet standards such as IPC-A-610 and ISO 13485, strictly control ESD and cleanliness in daily production, and provide complete documentation and process traceability for each board.

This article will first briefly explain the core requirements of medical PCB assembly in manufacturing, and then introduce 5 PCBA suppliers that can be given key consideration in China:

•  PCBasic

•  POE Electronics PCBA

•  Jabil

•  Kingford PCB

•  Luxshare Precision

Why Medical PCBA Needs More Than Standard PCB Assembly

If it is just an ordinary consumer electronic product, a PCB assembly is unqualified, the worst-case scenario is that the customer returns the goods, complains, or spending more money to redo a batch. In the field of medical PCBA, the failure of the same board may directly affect whether the equipment works reliably and may even impact user safety. This difference in consequences determines that the requirements and management methods for making consumer electronics and medical products are not on the same level.

Therefore, a truly qualified medical PCB assembly supplier should at least possess the following capabilities:

•  Maintain stable, auditable quality systems and provide solid evidence of them

•  Deliver full traceability for every single PCBA

•  Effectively control contamination, ESD, and process variation

•  Provide support for risk management and all documentation needed for audits

•  Offer engineering support when the customer is optimizing design for manufacturability (DFM) and design for testability (DFT)

In other words, what medical device enterprises truly need is a PCBA manufacturer that positions itself as a long-term partner and considers issues from the perspective of the entire product life cycle and compliance requirements, rather than a factory that only cares about production capacity and price.

IPC-A-610 – Workmanship for High-Reliability PCBA

IPC-A-610 defines the acceptability standards for electronic assembly. For medical PCBA, most customers will require Class 2 or Class 3 workmanship, including clean and reliable solder joints, strict criteria for voids, bridges, and wetting and controlled, procedure-based rework and repair processes.

ISO 13485 – Quality Systems for Medical Devices

ISO 13485 is the most core quality management standard in the field of medical devices. When a PCBA manufacturer has ISO 13485 certification, it indicates that all its production processes are fully documented in accordance with medical regulations requirements, that risk control, non-conformity handling and change management follow clear and defined procedures, and that the traceability of PCBA, from components to final products, is more complete and verifiable.

For medical device OEMs and start-up teams, ISO 13485 is often the most fundamental baseline for choosing a medical PCBA partner.

ESD Control – Protecting Sensitive Medical Electronics

Some devices may be potentially damaged by static electricity before failure becomes visible. Therefore, it is crucial to implement strict ESD control during the PCB assembly processing.

A mature PCBA supplier like PCBasic integrates ESD control into the daily production process to protect the long-term reliability of medical PCB assembly from the source.

UL, RoHS, and REACH – Material and Safety Compliance

Beyond how a PCBA is built, what it’s built from also matters:

•  UL: Safety and flammability ratings for laminates, plastics and insulation

•  RoHS: Restriction of hazardous substances like lead, cadmium, mercury

•  REACH: Control and declaration of chemicals of very great concern

A qualified medical PCBA manufacturer will provide complete materials and management documentation for relevant certifications such as UL, RoHS and REACH, which can make the submission of regulations and customer audits smoother for medical device OEMs. It can also provide reliable compliance guarantees for medical PCB assembly.

PCBasic – Engineering-Driven Medical PCB Assembly Partner

PCBasic is a PCBA manufacturer located in Shenzhen, specializing in high-mix, small to medium batch PCB assembly. This positioning makes it highly suitable for projects in the medical, industrial control, instrumentation and other fields that have extremely high reliability requirements rather than blindly pursuing low costs.

Positioning and Capabilities

PCBasic differs from other factories that mainly focus on mass production of consumer products. Its core lies in flexible, engineering-driven one-stop PCBA prototyping services. PCBasic integrates PCB manufacturing, component sourcing, SMT/ THT assembly, product testing, as well as conformal coating and box build assembly into one, providing a truly one-stop delivery for medical PCBA.

Focus on Medical PCBA and Controlled Processes

PCBasic regards medical PCBA as a high-reliability field, and the requirements for the process are much higher than those for regular orders. Its production line supports high-precision placement, uses nitrogen reflow soldering to ensure clean and stable solder joints, and is equipped with selective wave soldering to meet the requirements of mixed processes. The full-process AOI and X-ray inspection enable hidden solder joints to be controllable and traceable, allowing for the stable production of various medical products ranging from small diagnostic modules to complex control boards.

Quality, Traceability, Documentation

In medical PCB assembly, quality documents and traceability are as important as yield. The digital quality system of PCBasic covers incoming material inspection, batch tracking, process and operation records, as well as necessary test data archiving. Rework and non-conforming products are also strictly marked and subject to process management. Once problems occur, PCBasic can quickly locate the relevant batches and provide complete records, helping medical OEMs conduct risk analysis and meet regulatory requirements.

Engineering Support: DFM & DFT

Medical hardware is constantly iterated from prototype to clinical trials and then to trial production. PCBasic is particularly proficient in such projects. The engineering team can proactively inspect the manufacturability of Gerber, BOM and assembly drawings, optimize solder pads, stencil and solder thickness, and improve the yield of PCBA. At the same time, it can review the layout of test points to enhance the coverage of DFT and functional tests. Alternative recommendations can also be provided when the material delivery time is too long or production is halted. PCBasic is not only a PCBA manufacturer but also helps customers at the design level.

Testing Strategies

To ensure the reliability of medical PCBA (medical PCBA), PCBasic provides multiple layers of testing, including flying-probe testing for prototypes and small batches, ICT for higher-volume production, customized functional testing, and burn-in or environmental testing for certain products. The factory adjusts its testing strategy according to the stage of the project, making medical PCB assembly more controlled and predictable.
