PCB & MCPCB – Best Technology

What will make us keep moving? Somebody would say study, somebody would say competition, but I would say it is challenge. Because I deeply feel the power of the challenge in the past three months. BEST TECH took part in the “Operation Red Sea” which is an activity that PK with other five companies from July, 2018 to September, 2018. Although we were not the champion, we still realized our goal. During the competition, challenge not only brought pressure for us, but also teach our 3 things.

1. Never say never

Meeting the challenge just like you buy a stock, the stock will rise and fall when you possess it. At the beginning of the “Operation Red Sea”, everyone was enthusiastic and confident, but everyone’s passion began to cool down as for the front line stretched. Even began to deny ourselves when others far ahead. But fortunately we never say never and stuck to the end. It turns out that pushing yourself at the bottom of the valley will have unexpected effects — we have reached the goal that we set!

1. Believe in yourself—-I can make it

Maybe you are familiar with the story of Nick Vujicic. At the very beginning, he was born with defects and natural imperfection. He is an angel, but without wings. In the long life, it is no different from the car losing gasoline if he chooses not to believe in himself. Believe in yourself, you can make it better.

1. Attitude is altitude

Is a good attitude if we gave up when others further ahead than us? The answer is absolutely NO. the greatest disability is not having no arms and legs. The greatest disability is your mind, the choice that you make. No goal is too big, no dream is too far, because attitude is altitude!

Best, always be your best choice of PCB in China.

As the name implies, multi-layer PCB is that has multiple layers on one single board. It is like single or double-layer printed circuit board but in multi-layer PCB, the layers are substrate and copper coating over two layers.

Compared with the ordinary PCBs, the multi-layer PCBs are more difficult to fabricate. As it has multi layers that will make the manufacturing procedures getting complicated. Moreover, the fabrication process will be stricter. In order to provide the most satisfying service for customers, Best Technology continues to improve and develop more new products those meet the market needs. Currently, we can produce 20L-32L FR4 PCB.

Since manufacturing the multi-layer PCBs are not easy, then what are the difficult points to make the 14L IT180 PCB? There are three reasons as below for you reference:

1.       It is pretty thick

The thickness of it is more than 5mm. What’s more, the copper inside and outside are different, both of them are over 5OZ. Generally speaking, the thickness of ordinary PCBs is 1-2OZ. If the thickness is greater than and equal to 4OZ, it is called heavy copper PCBs. The copper thickness is related to the width and the line space. The line space is too narrow to etch and may cause short circuit.

2.       It has a certain difficulty to make coil board

This 14L IT180 heavy copper PCB belongs to coil board, so it has a certain difficulty to make. The coil board refers to a circuit board in which the wiring pattern is mainly winding, and the circuit board is replaced by an etched circuit instead of the conventional copper wire. If it is not a coil board, it is easier to etch the straight line on the board, but if it is a coil board, there is a certain requirement for the factory technology, because the surrounding shape of the coil needs to be carefully carved.

 3.       It has countersink

Because the countersink has certain requirements for angle and depth in the manufacturing process. In general, the countersink is easier to make if the angle is the multiple of 5. For example, the 90 degree angle is easier to make than the 85 degree angle.

This 14L IT180 heavy PCB possess a variety of advantages, so do not hesitate to send your orders if you would like to order multi-layer PCB and heavy copper PCB.

The extra thin printed circuit means the thickness of printed circuit board is thinner than the normal PCB. For most of FR4 PCB, min thickness is 0.3mm or 0.4mm, whatever it is 1L or 2L. For 4L, it will be more about 0.6mm.

But sometimes, limited to space or margin, or needed by design purpose, people needs extra thin such as 0.25mm, 0.20mm, or even 0.15mm board. For providing customers with the most suitable products and the most satisfactory services, Best Technology also made the extra thin printed circuit.

For this 2L FR4 PCB, we are able to make it to 0.15mm±0.1mm. Then you can use it in SIM card, sensor card and so on. As shown, it can also be rotated 180 degrees.

Besides, we are able to provide the extra thin PCB with or without soldermask, and copper thickness for 1/2OZ, 1OZ. It depends on the needs of the customers.
