0.15mm 2L Extra Thin PCB

September 8th, 2018

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 0.15mmÂ±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.

Since established in 2006, Best Technology is always dedicated to provide the most suitable products and the most satisfying service for customers, to be customers’ best partner of PCB and PCBA in China.

Tiny Pad for the Single Side Ceramic Board

September 5th, 2018

Â 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 (-55â„ƒ-850â„ƒ). Whatâ€™s more, it is good in dissipation and thermal.

Â 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.

: Picture1ï¼šThe obverse and the reverse side of the sample

Â 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.

Â 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.

Â The specifications as below:

Â The thickness of the copper: 35um

Â 1.0mm aluminum nitride

Â ENIG

Â Application temp: -55â„ƒ-850â„ƒ

The 12th Anniversary Celebration

July 11th, 2018

How time flies!

June 28^thÂ is the 12^thÂ birthday of Best Technology.

On this special day, we got together and had a big party to celebrate the successes of a year gone by and prepare for hard work to be rewarded in the new year.

When we think of yesterday, we never forget the sales amount is only $8,000.00 in 2006, but it will be around $8,000,000.00 this year.

Thanks to founderÂ PeterÂ and other memberâ€™s hard work, Best Technology keep growing day by day, and reach such a great achievementsÂ by far.

peter telling

Peter was telling us why we canÂ make it.

The reasons are:

We have rich experienceto manufacture Metal Core PCB (MCPCB), ceramic PCB and other kinds of PCBs, esp on some special boards such as heavy copper PCB (up to 30OZ), extra thin PCB (0.1-0.3mm), Rigid-flex circuits, so customers always only need to use us to meet all her different requirements of circuit boards.
We have our own raw material factory for MCPCB, we can control the quality from sourcing the material.
We can provide one-stop service(Manufacture PCB, source components and do SMT).
The most important reason is we are alwayshold on to our mission: to provide customer the most suitable product and most satisfied services.

cheers

Picture:Cheers

We are not only a best team, but also a harmonious family, we are together to fight for a better future in the coming 12 years.

Welcome Israel Friends visit us

April 27th, 2018

InÂ 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 themÂ to see our companyâ€™s video, which they knowÂ 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 areÂ following up with the SOP, to make sure quality is always controlled, and customer are interestingÂ in how we test the assembly boards using testing fixture.

Customer is very happy with our SMT procedureÂ and become more confident in placing more circuit board and PCBA order with Best Technology. After the meeting, we have a quick but deliciousÂ 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 memoriesÂ with each other.

AppreciateÂ again for theirÂ valuable time toÂ visit us, that’s our greatÂ pleasure toÂ have thatÂ forenoon with them.Â Look forward seeingÂ 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.

Soldermask on Hole (Via) Without Opening

October 6th, 2016

Soldermask opening always is a very important thing for various PCB, esp. for rigid FR4 PCB. In previous article, we already discussed why soldermask opening & tented was not the same like original gerber file.

If you really want soldermask opening for hole (Via) less than 0.60mm, you should added special notice when placing order.

At the same time, thereâ€™s another method you can use: To increase the soldermask opening diameter, that means add an â€œAnnular Ringâ€. Normally you will need to increase 0.10mm (4mil) on each side, so that thereâ€™ll be a 0.1mm â€œAnnular Ringâ€ around the hole/Via, that Annual ring will stop soldermask into the hole/via of PCB.

Because in a lot of design, if thereâ€™s Via/Hole, thereâ€™ll no opening in its soldermask file, maybe engineer think the drill will remove the soldermask and then thereâ€™ll no soldermask on these Via/hole of board. As mentioned before, if Via/Hole in Printed circuit board was less than 0.6mm, or around 0.65mm then itâ€™ll be a problem.

See from bellowing pictures of PCB board:

0.635mm Drill hole (Via)

(0.635mm Drill hole (Via)

This is the original PCB Gerber file, the diameter of drill hole was 0.635mm and thereâ€™s no soldermask opening on GTS (top soldermask) Gerber file. (Purple color was GTS, Yellow: GTL (top layer); Blue: Drill (PTH) file), and no Annular Ring.

So final circuit boards will be like belowing:

0.635mm Via covered/tented by soldermask

So you need to add at least 0.10mm (4mil) soldermask opening on each side of hole, so that thereâ€™ll be a 0.1mm Annular Ring, like bellowing:

Add 4mil Annular Ring on PCB Via

Then that hole will become like bellowing:

Hole/Via without soldermask (soldermask opened)

We believe thereâ€™re a lot of other handling method about that soldermask opening, please leave your comments, or contact us to discuss more about that, and believe you will be happy to receive with the PCB with correct soldermask opening!
