Uniwell Circuits Co., Ltd.is a professional Printed Circuit Board (PCB) manufacturer in Shenzhen,China. Founded in 2007, with 10 years’ development, Uniwell Circuits has met the highest international manufacturing standards by being approved for these quality certificates: ISO9001, ISO14001, TS16949. We are UL certified for single sided, double sided and multilayer PCB production, and adhere to all of the requirements for IPC and ROHS standards.

2.Raw material suppliers
The well-chosen types of raw material are well-known brand in PCB industry, which guarantees the steady product quality of Uniwell. More attention has been paid on th long-term relationship establishment between raw material suppliers and Uniwell to assure the stability and Reliability of the on-time material supply.

The friendly relationship leads to the mutual support and growing-up.
Here you may review our PCB laminate material Suppliers list. We offer these materials for fabrication of your printed circuit boards, such as glass fiber epoxy laminates, special high performance laminates, and more. Your choice of laminates will depend on your application. If you need assistance selecting the right material, please contact the helpful customer service representatives at Uniwell.

3.Test service
Prototype Orders: We offer Flying-Probe E-Test for small volume and prototype orders. Your circuit board (PCB) is checked through a device called a Flying-Probe E-Tester. The Flying probe testers we use have few restrictions on access, require no test fixtures, and can test boards with virtually unlimited number of nets. The Tester will check for short circuits, open circuits and make sure the nets of the PCB we made is the same as the nets in your design. After testing is complete, the fail rate of your boards will be less than 1%. 

Production Orders: We use Testing fixtures to test production orders. A bed of nails tester is a traditional electronic test fixture which has numerous pins inserted into holes in an Epoxy phenolic glass cloth laminated sheet (G-10) which are aligned using tooling pins to make contact with test points on a printed circuit board.

The fixture contains an array of small, spring-loaded pogo pins; each pogo pin makes contact with one node in the circuitry of the DUT (device under test). By pressing the DUT down against the bed of nails, reliable contact can be quickly and simultaneously made with hundreds or even thousands of individual test points within the circuitry of the DUT.

The Tester will check for short circuits, open circuits, and make sure the nets of the PCB we made is the same as the nets in your design. After testing is complete, the fail rate of your boards will be less than 0.1%.

AOI(Automated optical inspection)
We use an AOI to check the inner layers of multi-layers PCB. AOI visually scans the surface of the PCB. The board is lit by several light sources and observed by a scanner or by a number of high definition cameras. This enables the monitoring of all areas of the board.

AOI for a bare PCB board inspection will detect these features:
* Line width violations
* Spacing violations
* Excess copper
* Missing pads. ?I.e. a feature that should be on the board is missing
* Shorts circuits
* Cut traces or pads
* Hole breakage.( Breakout ) ?I.e. a drilled hole (via) is outside of its landing pad?
This inspection is much more reliable and repeatable than manual visual inspection.

The 3rd. ISO9001:2008
We are ISO 9001:2008 certified. And we briefly describe our quality control system as such:
* Our quality policy is a formal statement from our management, closely linked to our business and marketing plan and to our customer needs. Our quality policy is understood and followed at all levels and by all employees. Our employees will use measurable objectives to work towards.
* All Quality control data is recorded. Records will show how and where raw materials and products were processed, this allow products and possible problems to be traced to the source. Our quality control system is regularly audited and evaluated for conformance and effectiveness.
*Our quality control system records the customer requirements and creates a system for communicating with customers about product information, inquiries, contracts, orders, feedback and complaints.
* We regularly review performance of our quality control system through internal audits and meetings. We determine whether or not the quality system is working and what improvements can be made. We will deal with past problems and potential problems. Our system keeps records of these activities and the resulting decisions, and monitors their effectiveness.
* We documented the procedures for dealing with actual and potential non-conformances (problems involving suppliers or customers, or internal problems). Our system makes sure that all product(s) deemed “BAD” are quarantined and that no one can use the bad product until we can determine what to do with said bad product, We will seek and deal with the root cause of the problem(s) and keep records to use as a tool to improve our system.

The 4th . UL:E472163
Our products comply with UL safety certification 94V-0. Our UL number is E472163. All our PCBs meet a flame rating 94V-0 and satisfy all UL requirements. The flame rating per UL 94 defines a polymeric part 's resistance to fire. Typical ratings for PCB material are 94V-1 or better. The lower the number, the higher the flame rating (e.g., 94V-0 has a higher rating than 94V-1).
We are UL certified and our company logo can be traced back to UL 's authorized PCB manufacturers list. To be authorized in this category, a PCB manufacturer is subject to independent UL inspections of its manufacturing process and materials.  

RoHS
The Restriction of Hazardous Substances Directive or RoHS was adopted in February 2003 by the European Union. The RoHS directive took effect on July 1, 2006, and is required to be enforced and become law in each member state. This directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment.
From July 1st 2006 electrical and electronic equipment introduced onto the Europe market must not contain lead, mercury, cadmium, hexavalent chromium, nor the flame retardants polybromide biphenyl, or polybromide diphenyl ether.
All our lead free finishings: Lead free HAL, Immersion silver, ENIG and OSP all comply with the RoHS requirements.
