PCB Quality assurance

Quality Assurance Guarantee

The aim of the RayMing’s quality assurance work is a zero defect product with on time delivery. In order to achieve this we work both pro-actively and re-actively. This approach is standardised and carried out by the Factory Management organization. factory production – process control All of our factories are ISO 9001 and ISO 14001 certified. We monitor factory management systems as part of our audit.

Quality Management System


Quality Management

Rayming, ISO9001 certified PCB assembly house, operates under Shenzhen China operating procedures for all quality and process controls. These procedures assure that our product satisfies customer requirements in every stage and aspect of a development; from the selection of the suppliers to WIP inspection, and through to outgoing inspection and customer service. Here are just a few specific examples:


Preparation, Review And Control Of Manufacturing Instruction

Rayming will evaluate all the requirements after receiving the customers' design data and related document. Then, transform the design datum into manufacturing datum by CAM. Finally, a MI which incorporates the manufacturing datum will be formulated according to Rayming's real manufacturing process and technologies. MI must be reviewed after preparation by independent engineers. Before the MI is issued, it must be reviewed by QA engineers and get approved. Drilling and routing datum must be confirmed by first article inspection before issued. In a word, Rayming makes ways to guarantee that the manufacturing documentation is right and valid.


Final Control And Inspection

In Rayming, all PCBs must go through the open and short test as well as visual inspection after passed the relative physical tests. Rayming owns various advanced test equipments including AOI Testing, 3D AOI Testing, 3D SPI Testing, X-ray inspection and In-Circuit Testing for finished PCB assembly.


Evaluation And Audit Of our Suppliers

Suppliers must be evaluated before approval by Rayming's supplier evaluation team. In addition, Rayming will appraise and rank every supplier once a year to guarantee the suppliers provide the quality materials meeting Rayming's requirements. Furthermore, Bittele continuously develops suppliers and promotes them to improve their quality and environment management basing on the systems of ISO9001.


Incoming Control IQC

In Rayming, all materials must be verified and approved before going to the warehouse. Rayming establishes strict verifying procedures and working instructions to control the incoming. Furthermore, Rayming owns various precise inspection instruments and equipment to guarantee the capability to rightly judge whether the verified material is good or not. Rayming applies a computer system to manage materials, which guarantees that materials are used by first-in-first-out. When one material gets close to expiry date, the system will issue a warning, which ensures that materials are used up before expiry or verified before use.


Outgoing Audit And Approval

Rayming sets up a special function, FQA to inspect the products according to the customer's spec and requirements by sampling. Products must be approved before packing. Before delivered, FQA must 100% audit every shipment for the fabrication part number, customer's part number, quantity, destination address and packing list etc.


Contract Review

Before accepting an order, Rayming shall review and verify customer's requirements to make sure that Rayming has the capability to satisfy customers' requirements including specification, delivery and other demands.


Process Controls Of Fabrication

Right manufacturing instruction (MI), total equipment management and maintenance, strict WIP inspection and monitoring as well as working instructions, all these make the whole production process totally controlled. Various precise inspection equipments including the AOI inspection system as well as perfect WIP inspection instructions and control plan, all these guarantee that semi-products and final products, all reach the requirements of customers' spec.


Customer Service

Rayming sets up a professional customer service team to proactively communicate with customers and timely deal with the customers' feedback. If necessary, they will cooperate with the customers to solve the relative problems on the customers' site. Rayming is highly concerned about customers' needs and periodically surveys customers to learn about their requirements. Then Bittele will timely adjust the customer service and make the products meet customers' needs.

All PCBs Guaranteed to be Manufactured to Your Specifications

Our PCB guarantee goes beyond a declaration on a piece of paper. It’s a functioning system that ensures that your printed circuit board order is manufactured to your specifications. The system creates a framework for clearly defining the control of printed circuit board materials, processes, and verification activities, thus providing our customers with confidence that the manufacture of printed circuit boards is performed in a well-defined and controlled environment.

Great service, highly recommend for PCB board manufacturing, very good quality
Had a wonderful experience with Stan. He is very professional and works diligently. responsiveness is fast, most impotant,they fix our bug before produciton.
Awesome company! They beat my current supplier, is difficutl to find a trust pcba manufacturer, Raypcb is the one, we work togeher more than 6 years, never disappointed
I have had excellent service from Raypcb over the years. Your engineers have helped me and saved me many times.
PCB Electrical Test

We keep investing on test equipments to ensure quality

Flying Probe Test

Flying probe test systems require no test fixturing, have few restrictions on board access, and can test boards with virtually unlimited number of nets. These systems also allow developers to complete test programs in a short time. ,we have a number ofFlying Probe machines to ensure prototype quality and fast delivery

AOI Test

AOI is a key technique used in the manufacture and test of electronics printed circuit boards, PCBs. Automatic optical inspection, AOI enables fast and accurate inspection of electronics assemblies and in particular PCBs to ensure that the quality of product leaving the production line is high and the items are built correctly and without manufacturing faults

ICT Test

In-Circuit Test, ICT is a powerful tool for printed circuit board test. Using a bed of nails in-circuit test equipment it is possible gain access to the circuit nodes on a board and measure the performance of the components regardless of the other components connected to them.
