Liard Optoelectronics Beijing Yizhuang Production Base Phase I capped

On June 18, Liard Optoelectronics Co., Ltd. held a capping ceremony at the Yizhuang production base in Beijing. At the ceremony, Dr. Li Jun, Chairman of Liard Optoelectronics Co., Ltd. announced that Liard will build an LED TV and lighting industry chain in Yizhuang and build a world-class LED application industry kingdom.

Li Jun, chairman of the Liard Optoelectronics Co., Ltd. pointed out that the total area of ​​the Liede Yizhuang Manufacturing Industrial Park is 140,000 square meters. The total area of ​​the three buildings is 40,000 square meters. After the completion of the first three phases, Liard Optoelectronics Co., Ltd. will be involved in the construction of the later projects as soon as possible.

Liard Optoelectronics Co., Ltd. Yizhuang Development Zone LED Application Products Industrial Park, planning 140,000 square meters, the first phase of three buildings capped. They are respectively: 1# lighting lighting creative display debugging workshop, office building; 2# electronic machining workshop; 3# machining workshop, the first phase covers an area of ​​40,000 square meters. It is expected that the first phase of renovation will be put into production at the end of October 2013. In the future, we will create a new industrial chain in the field of LED TV and LED lighting.

Prototype PCB , also could call PCB Prototype . It's the PCB Board just finished design and need manufacture some small quantity PCB for testing. Normally, for the PCB manufacture job less than 0.2SQM, we would treat it as PCB prototype job. And for PCB prototype job, we could do 24 hours expedite service for 1-2 layer PCB, 48 hours expedite service for 4 layer PCB and 72 hours expedite service for 6 layer PCB.

The copper is the circuits material and the circuits designed by the PCB designers. Depends on the current in the circuits, the PCB copper thickness could be done with 0.5oz-10oz. But the PCB designers need be noted that the copper track width/space need be enlarged with the thickness. For example, the minimum copper track width/space could be 3mil/3mil with 0.5oz, but would be 4mil/4mil with 1oz.


The PCB board could be rigid PCB, could be flex PCB and also could be Flex-Rigid PCB. And the materials could be FR4, PI, Aluminum, Copper-based, Rogers, Teflon, etc. They have different applications. For example, FR4 PCB is the most commonly used for rigid PCB and almost good for all electronics products; PI is the most commonly used for flex PCB; Aluminum and copper-based have good thermal diffusivity and always used for LED PCB ; Rogers PCB and Teflon PCB are always used for High Frequency PCB, etc.


We are the one-stop shop for all kinds of PCB manufacture service from PCB prototype to big volume, which could save our customers a lot of time and money.
