Printed circuit board quality control

1. Selection of high quality suppliers: World Peace Group, Avnet Group (8 suppliers)

The special material inspection department ensures that the components are from the original brand and can eliminate the defectivefrom the source.

2. Professional quality testing team

Material inspection: The quality of the material determines the life cycle and service life of the PCB. All materials in FASTPCBA can be used in the factory after strict inspection.

Solder Paste Printing Test: Introduced the Korean SPI solder paste detector to detect the height, area, volume and displacement of the tin spot, avoiding problems such as less tin, more tin, missing printing, etc., to ensure the accuracy of solder paste printing.

IPQC check materials: Refer to the engineering drawings and BOM to measure and inspect each material of the first-piece board to ensure that the components attached to the production model are consistent with the engineering drawings and BOM.

SMT first-piecetest: Refer to Bom and gerber data to measure and test each material of the first-pieceboard to ensure that the components attached to the production model are completely in line with the customer's requirements and prevent the defective productsflow into the next process.

DIP process inspection: Before the DIP process, it will train and explain the attention points of the plug-in with direction or pinspecial components, and arrange the quality inspection staff to carry out uninterrupted inspection during theDIPprocess to ensure the quality of the DIP.

QA shipment inspection: According to each product craftguide and each postguide, all production processes are spot-checked to ensure that the package is shipped after passing the test.

9 inspection steps are strictly controlled:

A.IQC incoming inspection

Purpose of inspection: to prevent the bad process caused by defectivematerials on the line, and delay delivery

Inspection standards: IPC610 inspection standard, AQL sampling standard.

Inspection equipment: 60x optical microscope, electronic bridge

B.SPI solder paste inspection

Purpose of inspection: Early detection of the previous process operation flow out tothe next process

Inspection standard: 3D detection + statistical analysis of data

Inspection equipment: KY8080, KY8030XS

C.Online AOI testing

Purpose of inspection: Check whether the products produced are faulty or not, and the defectivematerials flow out of the next process.

D.SMT first piece detection

Inspection purpose: to ensure that the components attached to the production model are completely in line with the customer's assembly drawing and bill of materials, and prevent the defectiveflow into the next process.

Inspection standard: Refer to Bom and craftdocumentation to measure and test each material of the first-pieceboard.

Inspection equipment: O7-715-09405, QK-416-00648

E.IPQC product inspection

Purpose of inspection: random inspection of all production processes, whether it is consistent with the operation instructions

Inspection standard: each product craftguide and each postguide

F.Offline AOI detection

Inspection purpose: Check the PCBA of the surface mountthat has been soldered for the faulty,leakage,reverse, virtual,connection

Inspection equipment: ALD515

G.X-RAY-welding inspection

Inspection purpose: to detect the solder joints of the invisible parts of the naked eye, to avoid the short circuit of the virtual welding from flowing out tothe next process

Inspection equipment: SS-VIEW 2000

H.QC manual inspection

Refer to the standard IPC-610 inspection standard to inspect the finished board to ensure 99.98% of good products are shipped.

I.QA shipment inspection

Standardize shipment inspection of finished products to prevent unqualified products from being shipped, 40 times magnifying glass, microscope

FASTPCBA product quality control concept:

Quality is the foundation of enterprise survival and development. To improve product quality, all employees must participate in. Every employee has the obligation and responsibility to do product quality well, and firmly establish quality awareness, and strictly control and implement the product operation process. Leaders and every employee are required to devote themselves to product quality management and instill quality goals in the hearts of every employee to ensure the overall quality of the product.
