A PCBA supplier is a third-party manufacturer that assembles printed circuit boards (PCBs) with electronic components to be semi-products or end-products labeled your brand. Being cheap is not the only criterion for choosing a PCBA supplier for your EMS manufacturing. To save your fabrication budget, the vital is an optimal PCB design. A professional PCBA supplier can optimize your design and save your time, energy, and costs to the best degree, and you can yield successful results without worries about quality.

The most professional PCBA supplier you can work with is PCBONLINE, a one-stop source factory EMS manufacturer.

PCBONLINE provides professional engineering support throughout your project until you receive the products and yield satisfying results. You can hand over PCB design optimization, BOM integration/component sourcing, design for manufacturing (DFM), PCB fabrication and assembly, box build enclosure design, box build assembly, and even the manual design to PCBONLINE.


PCBONLINE is a one-stop PCBA supplier for middle and high-end fields for automotive, medical, aerospace, aviation, defense, industrial, computer, communications, and consumer electronics.

PCB and PCBA manufacturer

PCBONLINE has two large advanced PCB manufacturing in Jiangsu and Jiangxi and one PCB assembly factory in Shenzhen of Guangdong. Its first PCB factory was founded in 1999. And PCBONLIEN has over 10 years of experience in one-stop EMS manufacturing for clients around the globe.

Today, PCBONLINE has 60+ software engineers, 45+ hardware engineers, 560+ senior PCB/PCBA technicians, and complete materials and electronic component supply chains.

The PCB and PCBA manufacturing from PCBONLINE is certified with ISO 9001:2015, IATF 16949, REACH, RoHS, and UL. You can check PCBONLINE's quality certificates.

PCB fabrication from PCBONLINE follows the IPC-A-600 standards, and PCBA manufacturing follows the IPC-A-610 Class 2/3 standards.

All electronic components that PCBONLINE sources are from original factories and direct first-class suppliers that have been audited and have long-term cooperation with.

Besides, PCB prototype and PCBA sample manufacturing happen on production lines same as bulky PCB/PCBA orders.

How Does the PCBA Supplier PCBONLINE Empower Your Project?

PCBA engineering

When you send your Gerber and BOM to PCBONLINE at info@pcbonline.com, the engineers get involved in your project until the delivery. Professional engineers with 20+ years of experience review your documents, and you have a specialized sales engineer to follow up with.

Unlike most PCBA suppliers who put into production when they confirm the feasibility of PCB fabrication, PCBONLINE furthers analysis of your design to make it optimal before production. Over years, many clients are satisfied with the free PCB improvement assistance from PCBONLINE.

The PCBA engineer from PCBONLINE integrates your BOM and checks which components can be sourced and which cannot. PCBONLINE can source all basic components, but some active components may be hard to find out. For components that can't be sourced, PCBONLINE can use local alternative components to replace them and will ask if you agree.

component sourcing

It takes a short period of time for PCBONLINE to source all the electronic components on your BOM. Keep in mind that component sourcing takes up the most time in a PCBA project fabrication cycle. With a shorter PCBA delivery period, you can realize your design into end products and launch the market sooner.

Besides, PCBONLINE provides free design for manufacturing (DFM).

And in PCB fabrication, PCBONLINE will fabricate the prototype boards for your to confirm. And in PCB assembly, PCBONLINE fabricates 5 pieces of PCBA samples and randomly picks up one piece for the first article inspection (FAI). After the FAI, PCBONLINE will send an FAI report that records all specifications of the PCBA for you to review. Only after your approval, PCBONLINE will start the batch PCBA production.

For bulky PCBA manufacturing, it takes two to three work days for PCBONLINE to complete the assembly. For expedited orders, PCBONLINE can take the two-shift mode to work through the day and overnight to make sure of timely delivery.

What Services Does PCBONLINE Provide?

PCBONLINE provides one-stop PCB assembly services meeting all your demands.
