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.

Soldermask on Hole (Via) Without Opening
Thursday, 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, there’s another method you can use: To increase the soldermask opening diameter, that means add an “Annular Ring”. Normally you will need to increase 0.10mm (4mil) on each side, so that there’ll be a 0.1mm “Annular Ring” around the hole/Via, that Annual ring will stop soldermask into the hole/via of PCB.

Because in a lot of design, if there’s Via/Hole, there’ll no opening in its soldermask file, maybe engineer think the drill will remove the soldermask and then there’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 it’ll be a problem.

See from bellowing pictures of PCB board:

0.635mm Drill hole (Via)

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 there’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

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 there’ll be a 0.1mm Annular Ring, like bellowing:

Add 4mil Annular Ring on PCB Via

Add 4mil Annular Ring on PCB Via

 

 

 

 

 

 

 

 

 

 

Then that hole will become like bellowing:

Hole/Via without soldermask (soldermask opened)

Hole/Via without soldermask (soldermask opened)

 

 

 

 

 

 

 

 

 

 

We believe there’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!

Why Soldermask Opening or Tented was not the same like the Original Gerber file?
Monday, August 29th, 2016

Recently customer compliant that the soldermask for some holes, esp for PTH (plated through hole, sometimes people named Via) was wrong, because in his original Gerber file, it was opened, but on actual printed circuit board, it was tented (covered), and some cases, some was tented and some was opened at the same time. It made customer confused.

In fact, there’s a default rule in PCB (printed circuit board) manufacturing: If the PTH (Via) was less than 0.60mm, then the soldermask will be made as per factory’s default rules: making them as tented (covered), regardless it was tented or opened in customers’ original Gerber file.

Here you can see pictures showing a board with a 0.30mm PTH, soldermask was opened in original Gerber file, but in real board, it was tented.

0.3mm Via soldermask

0.3mm Via soldermask

And in this board, for 0.508mm PTH (via), some soldermask was opened and some was opened.

0.508mm Via soldermask

0.508mm Via soldermask

Why like that? Here are two major reasons:

1) For PTH(via) less than 0.6mm, normally the function was only to electrically connected trace, not for electronic components assembled; so whatever PTH was opened or tented, it doesn’t matter.
2) In rigid printed circuit board manufacturing, it’s not easy to etch away the soldermask around PTH less than 0.60mm. As soldermask was made by that method: printed whole area with oil (soldermask), then undergo develop & exposure, then pass the etching line. The chemical will etch away the oil accordingly to the drawing, but if the hole was too small (less than 0.60mm), then the oil around will be very difficult to etch away, so you will see some oil was etched away (soldermask opened), some oil still here (soldermask tented)

If diameter of hole was bigger than 0.60mm, then it’ll be easy to etch away and some of them will be used in assembly, so we will make according to Gerber file and you will see the board exactly like the drawing. See bellowing a picture showing a board with 0.889mm (0.035mil) PTH.

0.889mm Via soldermask opening

0.889mm Via soldermask opening

Sometimes, people just use these hole as testing point, not for assembly, then we suggest to add another PAD connected to this hole so that you can test it easy. To tested on hole was not stable as tested on a PAD.

In a conclusion, in future, if the hole was less than 0.60mm and you really want it to be opened, please add special notes when release order, and allow us to enlarge the opening diameter of soldermask (around 0.60mm) so that soldermask of these holes will be opened.

Please contact us if still any question about soldermask opening.

What will cause the solder mask layer blister and fall off?
Friday, April 8th, 2016

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.
