5G Will Drive the Development of PCB

Wednesday, September 19th, 2018

As the basic material of the digital products, PCB possesses a vast market. It can be applied to a variety of industries, including communications, computers, digital products and automobiles. Communications and computers account for the largest part.

5G era is around the corner, and China plans to achieve official commercialization of 5G network by 2020. The development of 5G puts higher requirements on the performance of PCB substrate, especially reflected in the followings:

1.      Low loss, high reliability

2.      High frequency

3.      High frequency PCB structure

4.      Low cost


It is reported that 5G RF (radio frequency) will introduce Massive MIMO technology that requires communication with a wider spectrum and wider bandwidth in the millimeter wave band. Compared with the number of million-level base stations in the 4G era, the development of millimeter waves will promote the scale of base stations to exceed tens of millions in the 5G era.

It can be predicted that the full commercialization of 5G will push the construction and upgrading of the communication base stations. As a result, there will be a huge demand for high-frequency and high-speed PCB, and the PCB will meet the needs of a new round of upgrading and replacement.

Tiny Pad for the Single Side Ceramic Board

Wednesday, September 5th, 2018

  In order to become the most creditable partner of customers, Best Technology is dedicated to develop the products that can meet the market all the time.The ceramic board has good prospects in the market because of its advantages. To begin with, it has resistance in very high or very low temperature (-55℃-850℃). What’s more, it is good in dissipation and thermal.

  For providing customers with the most suitable products and the most satisfactory services, Best Technology made a new single side ceramic board currently. It has a layer white solder mask in front and 1.0mm aluminum nitride in the back. Maybe it seems like aluminum substrate from the obverse side, but turning around you can know it is a ceramic board.

The obverse and the reverse side of the sample

Picture1:The obverse and the reverse side of the sample

  The most distinctive feature of it is that the pads on the surface are very tiny, and each small pad is combined into a circle just like the earth. Compared with other ceramic boards, the circuit of it is very small, too.

  The ceramic board has various advantages, it also can be applied in high power LED, solid state relay, electric power transmitter modules and so on.

  The specifications as below:

  The thickness of the copper: 35um

  1.0mm aluminum nitride


  Application temp: -55℃-850℃

  If you want to know more details about the ceramic board, please visit our website:

Meanwhile, the customers also wanted to visit our factory of printed circuit board to see the production process and capacity of the printed circuit board. So after the short meeting, we took the customers to visit the different workshops of production and explained the details that need to be paid attention to in each process of production.

  The customers were really satisfied with our services and looked forward to our next cooperation.

Welcome Israel Friends visit us

Friday, April 27th, 2018

In the morning of April 24th, 2018, our customer from Israel visited our company. They are very nice and easygoing.

Firstly we had a short meeting in our office to discuss some PCBA projects and component, also we invite them to see our company’s video, which they know more about our capability on PCB, Rigid-flex circuit, FPC, metal core PCB, Ceramic PCB and lead time for different circuit boards.


After that, we moved to our SMT plant, where is only 15 minutes far from our office.

In our PCB Assembly plant, we show customers PCBA (SMT) process: First put PCB on Auto-loading machine, then transfer to Auto-Solder-paste-printer, after than go to the next step of components pick & place by SMT machine, after visual checking, board will go throw to reflow oven, QC will check each piece of board after reflowing and then do function testing, or move to AOI process to make sure all components are on the correct position and direction, as well as X-ray testing for the boards with BGA.


Each step was monitor and operators are following up with the SOP, to make sure quality is always controlled, and customer are interesting in how we test the assembly boards using testing fixture.



Customer is very happy with our SMT procedure and become more confident in placing more circuit board and PCBA order with Best Technology. After the meeting, we have a quick but delicious Chinese lunch together. And we will visit that customer in the end of May and believe by that time, we can do more things together, as well as good memories with each other.

Appreciate again for their valuable time to visit us, that’s our great pleasure to have that forenoon with them. Look forward seeing them again in Israel in the end of May.

We always welcome customer to visit us, so that they can know about what we can make, not only providing various types of printed circuit board, but also always supporting customer best service with good price.

What the Maximum Current the Thick Film Ceramic PCB can be Carried?

Tuesday, January 27th, 2015

A lot of customers ask us what the biggest current his circuit can be carried, or how can I got a 6 Amps trace? We believe most of engineer design the thick film ceramic PCB, he will consider that, so we share information bellowing and hope it’ll be helpful for you.

When you try to know current, you also need to know the watts of trace will be, and then need to know the power density of thick film ceramic PCB firstly. The power density for conductor itself should be limited to max 600 Watt/inch2 of conductor surface. And power density for an Al2O3 substrate should be limited to 8 Watts/in2 (for the total of all conductors on top of it).

If you have a Ag conductor line of 0.3inch long, 0.010 inch wide (=30 square (0.3/0.01)), the surface area is 0.3 x 0.01 = 0.003 in2. This means the carrying powder P is limited to 600 (power density) x 0.003 (area) = 1.8 watts.

Assume conductor resistivity is 6mOhm/sq/12.5um (material P/N: ESL9562), the resistance value R = 30 sq x 6mOhm = 0.18 ohm.

Power = I2 x R, or I2 =Power/R=1.8/0.18 = 10, so the carrying current limit I = 3.16 amps. Or in a short equation,

I (amps) = line width (inch) x (power density)1/2 / (sheet resistance, ohm) 1/2

  1. If the trace keep 0.3 inch long, but change width to 0.02inch, (=15 square (0.3/0.02), the surface area is 0.3 x 0.02 = 0.006 in2. This means the carrying powder P is limited to 600 (power density) x 0.006 (area) = 6 watts.
    And resistance value for that trace will be 15 square x 6mOhm = 0.09 ohm, and then 3.6/0.09= 40, I=6.325 amps.
  2. If the trace width keep 0.01inch, but change line to 0.6 inch long (=60 square (0.6/0.01), the surface area is 0.6 x 0.01 = 0.006 in2. This means the carrying powder P is the same as 6 watts. (600×0.006).
    But the resistance value for that trace will change to be 60 square x 6mOhm = 0.36 ohm, and then 3.6/0.36= 10, I=3.16 amps. So you can see, it’s no useful to change the trace line.

So if you want to have bigger current for thick film ceramic PCB, then you need to increase the width of trace.

Hope above is clear for everybody. Please leave your comments on that power density of thick film ceramic PCB.

Bigger size of Ceramic PCB is Available Now!

Wednesday, December 10th, 2014

Good news! This month we have used a new machine which can print much bigger size of silver palladium, Gold palladium, and glass glaze on Thick Film Ceramic PCB.

Currently the normal dimension in thick film Ceramic PCB is about 80 x 138mm and that size has already limited a lot of designs. You can’t put too much trace, PAD on such smaller size board, and the you have to use 2 layer, or 4 layers ceramic board to put more trace. And of course, that will increase a lot of cost definitely!

Now, we can make 200 x 200mm (8×8 inch). Thinking about the normal 80x138mm and you will find out this is an extreme improving! See bellowing pictures show the comparing!

So now you don’t need to worry about the size! You can design as big as you want!

And we are also continuing to adopt first-of-art machine and technology to make bigger size, higher quality Ceramic PCB!

Please contact us if you have more good idea, or suggestion about Ceramic PCB.
