PCB Assembly Standards

PCB Assembly standards follow IPC-A-610E Standard

Item Description	Item Description
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.	Incoming material inspection (IQC) Eliminate the aging loss caused by poor production process and unqualified quality of refurbished materials on the line.
Intelligent warehousing of materials Use an intelligent material rack management system to prevent the use of wrong materials and improve the pass rate of process quality.	SPI solder paste inspection Professionally inspect the standard of printing solder paste to ensure the high quality of soldering.
On-line AOI inspection Check whether the produced products have errors, omissions and inversions, and prevent bad products from flowing out of the next process.	SMT first article inspection Use advanced first article tester to confirm the correctness of the placement process of the production line and ensure that the parameters of each RC component are within the standard range.
IPQC product inspection Check whether the products produced are wrong or not, and to prevent bad products from flowing out of the next process.	Off-line AOI inspection According to the IPC610D standard, inspect the soldered surface mount PCBA for errors, omissions, and false connections.
X-Ray welding inspection Inspect the solder joints of invisible components to ensure the reliability of each solder ball of the BGA.	QC manual inspection Refers to the standard IPC--610 inspection standard, and the finished board is visually inspected to ensure 100 % Good products shipped.
Automatic soldering Machine soldering, unified standards, high reliability, beautiful and no cleaning.	Automatic splitter The automatic splitter for milling cutters is accurate and fast, and improves the reliability of PCBA components. Automatically take typesetting, avoid manual contact.
QA shipment inspection Inspect the solder joints of components invisible to the naked eye to ensure the reliability of each solder ball of the BGA.
