Quality Objectives

There is an SOP for every single link, with regular inspections and SPI automatic detection.

The Kingdee management system and production management through the MES system.

The first-pass yield rate of SMT mounting and DIP insertion exceeds 99%.

The fully automatic first article tester will be used for testing every two hours.

The personnel configuration is complete.

14 SMT mounting lines and 8 DIP insertion lines.

————

The personnel configuration is also very well - structured.

With 14 SMT mounting lines and 8 insertion lines, there are more than 290 employees, and the division of labor is very clear: HR personnel, order - trackers, deliverymen, planners, warehouse staff, BOM arrangement technicians, purchasers, In - Process Quality Control (IPQC) staff, Quality Control (QC) staff, Quality Assurance (QA) staff.

Engineers are divided into equipment engineers and electronics engineers, and there are also operators and workers. Naturally, the cost of such a configuration is much higher than that of ordinary factories.

High-end configuration, capable of producing high-end consumer electronic products.

High-end Route:

————

Dingchang in Guangzhou follows a high-end route. Each production line is equipped with a full-automatic board feeder, a full-automatic printer, an SPI solder paste inspection machine, three high-precision modular mounters, one high-precision multifunctional mounter, a reflow soldering oven with sixteen temperature zones, an AOI optical inspection machine. There are a total of fourteen brand-new full-automatic production lines. The first article inspection machine, X-ray inspection machine, and automatic component counting machine enable us to produce high-end consumer electronic products such as mobile phones, tablets, televisions, and Bluetooth devices.

Electronic Auxiliary Materials:

————

We use Japanese Senju as our electronic auxiliary materials, and the cost is more than four times higher than that used by ordinary factories.

Procurement of Electronic Components and PCBs:

————

We purchase 100% according to the brand specifications specified in the clients's BOM. We directly connect with the original chip manufacturers and their agents to ensure that the components are genuine and original. We have been collaborating with large PCB manufacturers and the source agents of electronic components for many years. The resources we possess can help clients save more costs and reduce risks.

Quality Control:

————

The company has established a strict quality control process. For the workflow in the SMT workshop, there is an SOP (Standard Operating Procedure) for every single step. Operators conduct regular inspections, and SPI automatically checks the printing results to detect issues like bridging, insufficient solder, and misalignment. Random deviations in the placement accuracy of the mounter are also monitored. The furnace temperature settings for each board type must meet the requirements of the furnace temperature curve for each test point, as factors such as board size, thickness, pad size, and multi - layer boards can all affect the soldering effect.

Process Control:

————

There is strict process control for every process, including the defect rate of PCBA after passing through the furnace.

First Article Inspection:

———— First article inspection is carried out. A fully automatic first article machine is used for testing every time there is a new line change or every two hours during in - line production to prevent incorrect programming or material loading by the operator.

ERP Management:

————

The Kingdee Cloud management system is adopted to manage the clients's BOM effectively, facilitating the verification of incoming materials from the clients and the quick placement of orders with suppliers for the part of alternative materials after inventory counting.

Quality Pass Rate Exceeds 99%:

————

For SMT mounting and DIP insertion processing, our quality target is to achieve a first - pass yield rate exceeding 99%.

Strictly implement SOP specifications.
