One-Stop OEM PCB Assembly Professional Turnkey PCBA

COMPANY PROFILES

We started to provide contract electronics design and manufacturing services in 2008, we are obsessed with providing the happiest manufacturing experience to our customers.

When our founders found it difficult to get technical support and always high-quality products from the manufacturers, they sprouted the vision to provide blissful electronics manufacturing services to others, they rented an old workshop and started the journey.

In over 15 years, with the same vision, we have designed, manufactured, and delivered 5,000+ projects for over 2,000 SMEs. The products are alive to us, not lifeless pieces of stuff.

Main Production Equipment

About the production equipment, our company has advanced and professional production equipment to ensure good and high quality.

Equipment Function
Inner and outer AOI machine It can perform AOI detection on inner and outer layers, confirm whether the circuit is qualified and access.
AVI Before FQC visual inspection, intercept bad appearance effectively and play the role of double insurance.
VCP Pattern Plating line The electroplating quality is more stable than the traditional electroplating line and greatly improves the output.
Ionic contamination tester This machine is needed in the physics laboratory to test the degree of ion contamination of the circuit board and avoid risks.
Unqualified Control Process

Regarding the management of non-conforming products in the production process, our company strictly follows the "non-conforming product management procedures". Quality control department, Engineering department, Production department, QA department, and Business department are responsible for resolving problems together.

Unqualified Control Process Flowchart
Quality Management
Quality Management Diagram
  • IQC (Incoming Quality Control)
  • PQC (Process Quality Control): First Article Inspection, PQC will go to each production machine for inspection every 2-4 hours (size, appearance). Quality management of semi-finished products in each process. We will send 2-5pcs semi-finished boards of each shift to the quality inspector until they confirm then continue production. Operator charge the quality inspection for the subsequently semi-finished boards, sign confirmation after approved. Quality inspector random inspections. Only they are qualified can be handed over to the next process.
  • FQC (Final Quality Control): (That is the finished product inspection before shipment), appearance inspection 100%, random inspections of board dimension by batch.
  • FQA (Final Quality Assurance): According to the inspection standards of FQC sampling verification, and finally control quality, and then double guarantee the PCB quality.
Test and Maintenance Workshop
Test and Maintenance Workshop View

Custom test service is provided according to client's requirements and products. A full range of testing services is offered, including:

  • AOI (Automatic Optical Inspection)
  • Function Testing
  • In Circuit Testing
  • Testing Fixtures
  • Testing Service
  • X-Ray for BGA Testing
  • Printing Solder Paste Test

Each board is carefully examined by our dedicated inspection team using AOI and high magnification viewers. Using our X-Ray machine, we test PCBs to component level and all wiring is fully inspected and tested. Flash testing and earth bonding tests can also be undertaken where required.

FAQ
Q1 What's your monthly capacity of PCB assembly?

Monthly 140 million points from SMT, 300K pieces from DIP.

Q2 How do you go quality control in PCB assembly?

We fully comply with ISO requirements and process in accordance with the Quality Management Manual for order management, production management, and process management, and strictly implement processes such as corrective and preventive measures and change management.

Q3 Can you source parts for me even if no assembly need?

Absolutely please provide us with your BOM or a list we will analyze the source make classified packaging attached with labels then send them to you.

Q4 What is your components procurement capability? Which supplier do you work with directly?

We have more than 40,000 part models in stock, and provide you with hard-to-get chip supply. Our parts are directly from the top level suppliers such as Microchip, TI, ARROW, AVNET, FUTURE, ELMENT, Digikey...

Q5 How do you go inventory management?

According to ISO process warehouse management operation guideline, we observe the principle of first-in-first-out of materials, and control the temperature (constant 25°C) and humidity (40% RH) of the warehouse with strict anti-static. Stock materials are managed separately according to different customers.

Q6 How are EOL (End of Life) materials handled?

1. If EOL happens in the running projects, the agent will send a production stoppage notice (Order & Supply deadline), and then our clients will get notified with our alternative suggestions.
2. For the projects transferred from other production source, we will source alternatives in advanced, or come up with and help our clients to change the design if no exact match alternatives.
3. For other cases, we will try to meet the short-term needs of customers based on our understanding of the market inventory situation.
