High Precision one stop turnkey PCB Assembly Services

Fast & High Precision & High Quality

Printed circuit assembly is a specific process and one that differs greatly from the manufacturing process for a traditional circuit board. PCB Design is a crucial element of manufacturing PCB, as is the process of creating a viable PCB prototype. Once a PCB is finalized, electronic components need to be soldered directly onto it in a precise way, given the goals of the result before it can be used in any type of electronic equipment or device that is typically considered the “brains” of the product.

The assembly process is dictated by a variety of factors – including the type of board, electronic components, the assembly technology used (I.e. SMT, PTH, COB, etc.), inspection and test methodologies, the purpose of the PCB assembly and more. These elements all require a process that requires a steady, experienced hand to help guide assets across all phases of production.

How to get a quote for Print Circuit Board Assembly (PCBA) Services?

Customer only needs to provide Gerber file, Bom (Bill of Materials ) list and Pick and Place file.

We focus on both Rigid PCB Assembly, and Flex PCB Assembly. Our quality driven PCB Assembly process ensures that your finished project is of the highest quality.

In Full Turn-Key PCB, we handle everything including making circuit boards, ordering components, online order tracking, quality inspection and final assembly.  In partial Turn-Key, you can order the PCBs and partial components, we will fix the remaining parts for you.

How to ensure quality in Turnkey PCB Assembly Service?

5 steps to making sure your product is 100% working

1. First Article Inspection (FAI)

FAI can be understood as the first piece quality inspection before the start of mass pcb assembly.

Is to avoid the large quantities defective that because of the process,operation or other reasons.

Each resistor,capacitance and inductance will be inspected by LCR meter.
The chips verified by QC with BOM and Assembly drawing.

2. Automatic Optic Inspection 

AOI device is for inspection the compoents placement and solder joint quality after SMT(Surface Mounted Technology).

To achieve better quality control,find and remove the errors early in the assembly process.

It is avoid the defective product to assembly,will avoid scrapping the repairable circuit board.

3. X-Ray inspection

X-ray is a very short wavelength of electromagnetic waves, the wavelength range of 0.0006 a 80nm,
with a strong penetration,X-ray could penetrate a variety of different density of the material.

When the design have BGA or QFN,for checking the solder quality that could not be visible by eyes.

We will use X-ray machine to inspect the BGA or QFN package in finished PCB assembly.

4. Final Quality Assuerance (FQA)

After all the above quality control processes,

Quality Engineer will make final quality visual inspection for the all product.

5. Functional Test

Functional Test are based on automated test tools to simulate a variety of normal, peak and abnormal load
conditions to test the performance of the final PCB assembly products.

Functional Test is a complex process,which include Tool made,Programming and testing,
need technicality support from customer.
