Quality Management

Tortai Electronics adheres to the PDCA management improvement principle, based on ISO9001, ISO13485, IATF16949, ISO14001 quality system and IPC-A-600H standard, to optimise the internal management process and to enhance the supply chain management level, in order to ensure that our customers receive high quality products and manufacturing services. We strictly control the quality control points in the process, NPI product introduction, DFM inspection, PCBA manufacturing and testing, and conduct full training to form a perfect quality management system.


DFM Inspection

Check the following items of customer design PCB, BOM, schematic, and finished assembly manual:

Document version and last update time

Process: leaded/lead-free

Clear component part numbers and silkscreen

BOM with manufacturer’s brand and material number, description, and bit number

Confirmation of PCB fabrication process: material, board thickness, copper thickness, number of layers, surface treatment, character colour and special processes.

Reasonable PCB layer and board assembly method.

Provide correct SMT mounting files

Perfect program burning and function test programme.

Clear assembly manuals and schematics for finished products

Other special process requirements


New Product Introduction Meeting (NPI)

Organise sales department, engineering department, production department, purchasing department, quality department and other personnel to hold a new product introduction meeting.

Detailed introduction of the customer’s project background, product application scope, delivery and special requirements

Determine the internal customer number and product number

Define the production batch, procurement and delivery quantity

Evaluate the difficulty of the process and key quality control points of the project.

Procurement of materials through regular channels such as primary agents and top traders.

Can provide the first-class agent certificate of origin

Good centralised purchasing advantages, shorter purchasing cycle, latest material year, stocking advantages, etc.

Provide perfect technical support from the original factory


IQC Incoming Material Inspection

Measure the thickness of PCB

Check the PCB through-hole and whether the ink is blocked, etc.

Check whether there is warping and deformation of PCB, and whether the silkscreen is clear.

Check the PCB for broken wires, skipped wires and other defects.

Place the PCB in the reflow soldering oven temperature test, check whether the yellowing or deformation

Check whether the batch number, material number and silkscreen of the incoming electronic components are consistent with the BOM.

The incoming electronic components are placed on the PCB bare board for pad or through-hole fit test.

Random inspection of incoming electronic components resistance, capacitance, etc., and compared with the BOM

Check the surface of the incoming electronic components whether there are scratches, deformation, broken legs, short legs and other appearance defects

Procurement of electronic components2

Component Storage And Solder Paste Printing

Storage of sensitive components in professional constant temperature and humidity chambers

Bake some PCB/IC/BGA with strict requirements for 2-12 hours to remove surface moisture and enhance solderability.

Adopting first-class brand solder paste

Develop high quality laser stencil

Perfect solder paste freezing, thawing and stirring operation procedure.

Equipped with fully automatic solder paste printing machine to ensure the consistency and reliability of solder paste printing during mass production.

Procurement of electronic components3

Use the oven temperature tester to check the oven temperature every 4 hours and record it.

Use AOI optical detector for batch detection of wrong parts, missing parts, reverse, false soldering and other defects.

Use X-Ray to build up boards containing dense ball BGAs.


DIP Plug-In Processing

Strict workstation operating instructions

Wave soldering fixtures are prescribed for mass production to ensure the reliability and consistency of soldering.

Equipped with 2 plug-in production lines to meet the needs of mass production

Equipped with engraving machine, the engineering department according to customer requirements to open the test rack, the ability to complete the mainstream chip programme burning and functional testing

DIP wave soldering


Quality Management System

Quality Management System (QMS) refers to the management system that directs and controls the organization in terms of quality. The quality management system is a systematic quality management mode established within the organization and necessary to achieve quality objectives. This is a strategic decision of the organization. It helps organizations to maintain quality standards and improve their performance over time.

Quality management systems help businesses identify potential problems before they occur, allowing them to take corrective action quickly and efficiently. They also help businesses stay organized by providing a systematic approach to quality assurance, ensuring that all processes are followed correctly and consistently. Quality management systems can also be used to measure performance, helping businesses identify areas for improvement and make necessary changes in order to keep up with changing customer needs.
