Every pcb board is manufactured in compliance to standards adopted by ISO 9001. This also ensures that product manufacture is done as per the customer's environmental and regulatory requirements. We have thrived in a highly competitive Printing Circuit Board industry primarily due to our unwavering commitment to meet the customer's specifications, quality and on-time delivery.

2.Company information
Uniwell circuits was founded in 2007, specialized in LED pcb manufacturing.
We can offer unique design and some our models, OEM&ODM are welcome. From our ISO9001:2008 certified factory, we can produce 10000 square meter of led pcbs per month, 100%testing guarantee stable quality, to meet custom's need.
Uniwell has gathered a large number of engineers who are outstanding in the domestic circuit design industry and have over 12  years of experience in design. We have specially set up the led bulb pcb, rigid led strip pcb, led tube pcb, ceiling light pcb, and led pcb built-in IC power driver.


3.Advantages of aluminum base PCB
1)Heat dissipation
Some LEDs dissipate between 2-5W of heat and failures occur when the heat from a LED is not properly removed; a LED’s light output is reduced as well as degradation when the heat remains stagnant in the LED package. The purpose of a MCPCB is to efficiently remove the heat from all topical IC’s (not just LEDs). The aluminum base and thermally conductive dielectric layer act as bridges between the IC’s and heat sink. One single heat sink is mounted directly to the aluminum base eliminating the need for multiple heat sinks on top of the surface mounted components.

2)Thermal expansion
Thermal expansion and contraction is the common nature of the substance, different CTE is different in thermal expansion. As its own characterics, aluminum and copper have unique advance than normal FR4, thermal conductivity can be 0.8~3.0 W/c.K.

3)Dimensional stability
It is clear that the size of the metal-based printed circuit board more stable than insulating materials. The size change of 2.5 ~ 3.0% when metal core pcb and aluminum sandwich panels was heated from 30 ℃ to 140 ~ 150 ℃. 

4)Less expensive.
Aluminum is indigenous to a variety of climates, so it’s easy to mine and refine. That makes it significantly less expensive to mine and refine than other metals. By extension, the manufacturing costs associated with products using aluminum are also less expensive. Aluminum PCBs are also a less expensive alternative to heat sinks. 

5)Friendly to the environment.
Aluminum is a non-toxic, recyclable metal. From the manufacturer through to the end consumer, using aluminum in PBCs contributes to a healthy planet. 

6)Very durable.
Aluminum is stronger and more durable than base materials like ceramic and fiberglass. It is very sturdy, and reduces accidental breakages that can occur throughout the manufacturing process, and during handling and everyday use. 

Considering its durability, aluminum is very lightweight. It adds strength and resilience to PCBs without adding additional weight.

4.Quality system
Uniwell Circuits has passed the certification of international quality system as TS16949 (2009), ISO14001 (2004),

ISO9001 (2008), UL certified, and all of its products follow the IPC, ROHS standards at present.The company strives to do world-class products and service, and continuously improve customers’ satisfaction is our pursuit of Goals.


5.Packaging & shipping
