​​

3.  Industry-Standard Quality Control

​

Quality is embedded at every stage of our Printed Circuit Board Assembly (PCBA) process. We adhere to globally recognized quality standards to ensure that every PCB meets performance, safety, and durability expectations before it reaches the customer.

 

Multi-Stage Quality Control Process​

a.  Incoming Material Inspection (IQC) – All electronic components and raw materials undergo rigorous visual inspection to verify authenticity, compliance, and specifications before assembly.
 

b.  In-Process Quality Checks (IPQC) – Our conveyor belt production lines integrate real-time monitoring at critical assembly stages to detect and correct issues before they escalate.

c.  Automated Optical Inspection (AOI) – High-resolution AOI systems scan PCBAs immediately after surface-mount technology (SMT) assembly for solder joint quality, misalignment, missing components, or defects.

​

d.  X-ray Inspection for BGA and Hidden Solder Joints – Advanced X-ray analysis is used for Ball Grid Array (BGA) components and hidden solder joints, ensuring strong and reliable connections.

​

e.  Functional Testing at Key Production Stages – PCBs are tested at multiple stages along the assembly line to ensure they function correctly before final integration into the complete product.

​

f.   Final Product Inspection (FQC) – At the end of the conveyor belt, fully assembled electronic products typically undergo a comprehensive final test to verify functionality and reliability before packaging.

 

However, some customer-specific PCBAs may not undergo this test due to factors such as:

 

i.   Incomplete assembly (e.g., missing mechanical enclosures or not provided).

ii.  No firmware is uploaded at this stage.

iii. No need for functional testing as per customer instructions.

iv. A functional tester was absent from the customer.

v.  Prototype-only builds, where testing is not required.

vi. The PCBA is not integrated into a final product, making full testing impractical.

​

JosephSan can integrate tailored quality control solutions upon request for customers requiring customized functional testing.

​​

g.   Packaging Quality Assurance – All products are securely packed in protective boxes, cartons, and pallets before shipment, preventing damage during transportation.

​

We don’t just build PCBAs – we embrace quality from start to finish, ensuring that every product leaving our factory meets the highest industry benchmarks.
