PCBA Quality Control Key Process

IQC

Mainly check if all the PCB,components, stencils,fixture meet the required specifications to avoid the quality issues from the begining.

PCB: thickness,flatness, delamination, dirty, oxidation, copper exposure, board edge burr, hole plugged,pads,silkscreen,circuits and soldermask,ect;

Components: part number and description, pin foot numbers and spacing,quantity,value,appearance and shape (deformation, broken pin, oxidation etc),temperature resistance,ect

Storage

Sensitive components:We have relative humidity 5% cabinet to store your sensitive chips

RoHS components: After IQC process, the outside package will be labeled with RoHS or Non RoHS remarks.

Solderpaste: we seal and store our solderpaste in 2-10℃ refrigerator and label them with expiration date.

Material identification card

Solderpaste

·We choose famous solderpaste brand like Senju, Alpha, Kelitai, Chuanze, etc.

·We apply automatic solder paste mixing machine to stir clockwise for 2-5 minutes until the solder paste reaches a filamentous state and immediately use for production.

·We only use famous brand laser stencil and pay highly attention to the high precision solderpads like QFN,BGA ect.

·Our 3D SPI controlling the solderpaste thickness,area, volume distribution with the non-contact laser 3D scanning intensive sampling technology.Workers can easily find out the solderpaste issue in this step to avoid soldering issues before the PCBA go into oven.

PCB SMT Soldering

① We have 4 automatic Pick&Place production lines, equipped with YAMAHA brand YSM10+YSM20R, electric feeders, perfectly achieve 0201, 01005 SMT precision, support common IC, BGA, QFN, PLCC and other components of precision package components assembly. Wrong material prevention system prevents workers from loading wrong components and causing quality accidents.

② Our reflow oven has 10 temperature zones, which will leave more time for solder paste mealting and solidification, make sure the temperature rising and dropping more steadily，this will help to prevent a lot of soldering quality problem caused by the thermal shock.

③ AOI equipment is used in the end of our every production lines. AOI machine automatically scans PCB through the camera and collects images to compare the actual solder joints with the qualified images in the database.This will easily find out the soldering issues and improve a lot our QC’s efficiency.

④ We have X-ray equipment to check the soldering quality for BGA chips.

⑤ The first article inspection is required before we can run the rest production. For example, the design information and designators and components value will be imported as a database to verify if the first article fully match the specifications of client’s design files.

④ We have X-ray equipment to check the soldering quality for BGA chips.

PCB Assembly Inspection

How do we make sure the testing instructions can be 100% follow?

·Project manager will maintain real-time communication with client and translate all instruction requirements for engineer.

·The engineer will train and guide the testers until they can understand all steps and operate independently.

·The test operation steps and test results will share with the customer with a video record for confirmation and archiving.

·After the test result is confirmed by the client, the tester will proceed 100% products.

·Failure test results will also be recorded and informed of how to resolve them and as a basis for future design improvements.

Package

PCBA board is a fragile and easily damaged product. We always carefully packed with bubble bags, pearl cotton, electrostatic bags

before transportation to prevent the damage causes by static and crushing.

PCB Packge

We adopted vaccume package for our PCBand place humidity identicator in every singlepackage to ensure max moisture resistance.

PCBA Package

For standard dimension PCBA we normalyadopted ESD bag and cardboards, or redbubble wrap and pearl wool combination toensure our PCBA can be protected well fromstatic electricity and crash.

For Large and Heavy PCBA

We adopted vaccume package for our PCBand place humidity identicator in every singlepackage to ensure max moisture resistance.
