Highfive Quality Control
Quality Control is One of Our Most Important Essential Factors
Quality is one of the most important specialties and essential factors.
All functions and performance of devices are based on project design & EMS. In one word, product design is the heart of electronic devices for quality.
How to ensure the quality and reliability of electronic devices is one of our key items for products.
Quality Control and Assurance from PCB Design to Assembly
Firstly, regarding PCB design performance, it can be testified and checked as we finished it. That even if the PCB design schematic is correct.
Subsequently, the PCB fabrication is most important for every process, not only for material selection, including every process of fabrication, and assembly.
Third, we would conduct debugging to check and verify whether the quality is good or not.
Even the PCB design and fabrication are perfect jobs, but there are some low-qualified processing with poor quality inspection and checking. The result would be poor as in this case.
Therefore, it’s especially important to implement quality checking, inspection, and we need to ensure all items are carried out based on a perfect quality control plan.
Quality Assurance can guarantee the quality for all items we need to care about in the process from PCB design to PCB manufacturing.
The task in quality control and assurance of PCBs comes primarily ineffective management, monitoring and checking, inspecting, verifying on PCB design, PCB Fabrication, and PCB Assembly, includign all mechanical parts, electronic parts, and manufacturing processes.
Anyone, the qulity is from Design, but not control, but we need to have all quality checing points to confirm whether we can assure all actions are perfect.
How to Ensure the Quality?
In order to ensure quality in PCB design. we need to conduct the following items:
Checking the Validity of PCB Design Files
We shall conduct the Cross-checking according to design rules and provide suggestions till all Engineering Questions are correct and ensured at Our engineering department.
There would have some Engineering questions for every project if there is any query from our engineers. And all questions need to be confirmed with us then we can start the next step. Not only for Lay out structure，lay-up, hole, line, space, BGA area, and so on.
The project leader should be responsible for checking PCB design data and corresponding approval procedures have to be implemented so that validity of PCB design files has to be ensured for project finishing.
Manufacturability of PCBs Assurance (Tooling Verify Processes)
Project leaders and experts would strictly confirm the requirements in order to ensure the manufacturability of PCBs.
Tech requirement can be directly listed on design drawings if it is relatively simple. Otherwise, it has to be summarized into a form that is Manufacturing Instructions.
Even it is a simple and easy requirement, it has to be explained as clear, accurate, and traceability.
As a value-added option for our services, Highfive can offer Free DFM Check. If any issue was found, our supporting teams would get in touch with you immediately to solve the issue.
Testability Based on Quality Control Plan
All Testing, checking, controlling items would be defined on the Quality Control Plan to standardize the implements for every test point’s structural style, dimensions, routing, hole and control characters so that we can ensure testability and manufacturability of project.
The Capability of PCB Matching
Highfive has four MFG sites for projects. We need to select one of them to start the fabrication according to the design files.
There are all extended custom manufacturing capabilities for a comprehensive range of PCBs, including, PCB prototyping and NPI/Pilot/Mass (Four Fabrication sites to match your flexible requirements).
High-Density Interconnection ( HDI）
Heavy Copper for Double/Multilayer PCBs
Metal Core PCB (Copper, Aluminium, Steel substrate, etc)
Impedance Control, Mixed Dielectric Base High-Frequency PCBs
Double-side and Multilayer PCBs
Specialties for PCB material
FR-4 Tg, Hi-Tg, Rogers, Roger +FR-4 Hybrid, Halogen-free, BT Epoxy, Teflon, Arlon, Taconics, RCC, Cyanate Ester, Polyimide, Nelson, Geek, Allied 408, CEM3, ceramic, PTFE, etc.
Double-Checking and Confirmation of PCB Files
Engineering engineers have to double-check and confirm the design files are correct prior to manufacturing. Sometimes, the PCB files have some versions of design files. So it’s necessary to for double-checking.
All Key Parameters Monitoring and Double-checking
The quality of key parameters must be monitored and checked, for example, including copper etching, via hole mentalization, pattern plating, etc.
In order to ensure avoid the wrong operations, for example, absence of burr, line space, line width, solder mask bridge, stack-up defect, and so on.
Quality control and assurance items would be shown on the MI( Manufacturing Instruction)
Highfive Specialties Based on Rich Engineering Experience
Highfive attention to detail and commitment to the customer in a small business environment delivers a quality product on time.
As EMS, electronic and electrical Solutions, PCB, and PCBA technologies change with time, we have kept pace with innovations and updated applications.
If you are exploring new concepts in any design, tell us about your choices in new materials.
We are centrally located in Guangdong, China, and have been in service for over 16 years. Our focus is on project prototype, NPI, Pilot, mass production, but help is also available in design, and assembly areas in these disciplines.
