Quality Control Process
The perfect quality assurance system and various testing equipment help us monitor the entire production process to ensure the stability of the process and product quality. At the same time, we also introduce advanced instruments and technical methods to achieve continuous improvement.
PCBAYCT has dozens of SMT production lines. Advanced production equipment, strict quality control and intelligent service system to ensure the standardization and best quality of each production process.
Smart management system & Advanced production and testing equipment
Quality checking process and description
01-Process review
Assess and inspect the particularity of the PCBA manufacturing process in advance, guide the production, and improve the quality from the process technology.
02-IQC Incoming Quality Control
● Check whether the resistance and capacitance values are correct ● Check whether the pads on the components and the board are consistent ● Confirm whether the incoming quantity is accurate ● Check whether the components are abnormal
03-SPI Solder Paste Inspection
SPI can detect whether the solder paste is sufficient and uniform, which can effectively prevent production quality problems in advance caused by poor solder paste printing.
04-Online AOI Inspection
The AOI can detect the wrong solder, reverse solder, false solder, empty solder, incomplete solder, short circuit, offset, tombstone, etc. after reflow soldering. And it can also detect excessive solder, less solder, continuous solder and other undesirable phenomena in the appearance of PCBA solder joints.
05-First sample test
Combined with Gerber, BOM and coordinate files, the resistance and capacitance in the completed PCBA are verified again by the first-sample tester to ensure the correctness of all parameter values.
06-Off-line AOI inspection
According to the IPC610D standard, inspect the soldered surface mount PCBA for errors, omissions, and false connections.
07-X-Ray welding inspection
Inspect the solder joints of invisible components to ensure the reliability of each solder ball of the BGA.
08-QC manual inspection
Refers to the standard IPC--610 inspection standard, and the finished board is visually inspected to ensure 100 % Good products shipped.
Resolving Quality Issues
If your order does not meet specifications, you will enjoy our rework or refund policy.
You can issue any complaint within 5 working days after receiving the products. Our after-sales service team will resolve these issues as soon as possible, usually within 1-3 working days. We promise that if quality problems are caused by fabrication, PCBATop will be responsible for free maintenance or rework.
