EBest Circuit (Best Technology) Co, Limited, establish on June 28, 2006, is a Hong Kong registered company that focused on MCPCB, FR4 PCB, Ceramic PCB, Special PCB such as Heavy Copper (up to 20 OZ), and PCB assembly service. EBest Circuit (Best Technology) has been established for ten years, and has been better and better, hope we can help you more in further.
Following information is the activity that our Sales Department celebrate the 10th for EBest Circuit (Best Technology) Co, Limited.

All of the three goods are customized for you by the EBest Circuit (Best Technology) Co., Limited. Hope you could enjoy them and we always are able to cooperate in the future.
Normally, we send the goods to customers by Express. But it’s only for a small quantity and light weight. If mass production, the quantity always big and with heavy weight. if still by Express, the shipping fee would be very high. It’s no economy.So we will choose to ship out by Sea or By air.
packed all the goods and making PL & CI.
Booking the shipping space, get the S/O, arrange the truck to pick up the goods and delievery to relatively port or airport.
Prepare the export customs files and do the customs clearance, files include declaration form, PL, CI,contract, Proxy and others customs needed.
Goods boarded the plane or sea, get the B/L, making import clearance files, including C/O,FA,FB,FE etc. Provide this files to consignees or their agent.
Consignees or their agent do the import clearance, pay the import fee, then to get the goods.
It is need about 4-7days to completely the process by air, 8-35 days by sea, depend on the Place of Delivery.
As PCB manufacturer we can provide turnkey and door to door service, meanwhile we also can help you if you have any shipping questions.
We always see the yellow surface in the DCB ceramic PCB surface although it does not affect the function, but looks unbeautiful. In order to strongly combine the copper with ceramic substrate, especially when the copper is little, the exposed more substrate we need to do a special sinters process under appropriate high temperature, so it caused.
It’s unavoidable, we need to check and choose the better to ship out.
Some customers may get PCB that includes blister on the solder mask layer, even the solder mask layer fall off. As PCB manufacturer, we will let you know what cause it and how to prevent on PCB manufacturing process. Please read the following information but don’t hesitate to contact us if you need more help.
The surface of copper is not clean and oxidation in previous processing. It need to strength the surface finishing of the boards and ensure to dry off the boards in previous processing.
The film was underexposed. It need to determinate and adjust the exposure energy of the boards.
The insufficient curing. It need to to check the heat uniformity of the dryer oven and control the curing temperature and time of boards.
Improper proportion of boards’ink. Pay more attention to the ink’s proportion when mixed.
We have installed a new high-speed (30,000 point/hour) SMT line which increase our production capability and more important, we imported new SMT machine with Panasonic, it’ll short the lead time of SMT.
By adding this new machine, we hope to provide you faster lead time of board SMT.

Via hole wall thickness is determined by the plating normally 1/2 OZ or 1 OZ is used based on your design application. Power boards will go for more Ounces.
For power signal via – it’s important to consider the current, temperature rise in PCB, plating, PCB material used.
According to IPC-6012, the standard via hole wall thickness is 15-18um. But Best Tech can make via wall with 40um.
If the hole copper thin, resistance, and wide current, fever, high temperature, especially in SMT and wave soldering) base material resin (high expansion coefficient) is prone to mechanical stress of hole copper, and the thermal stress, pore copper prone to mechanical fatigue, hole wall with micro cracks. There may be holes separation of copper and the inner pad.
It is a 2 layers stack up including via holes, and you can find the via wall details. BTW, there are via wall just when we do Plated Through Hole to connect Top layer and bottom layer.
