3 Notices for Layout Double-Side BGA for FPC

Layout double-side BGA for FPC is used in some products, but since the complexity of manufacturing process and maintainability need to be taken into consideration, the designers need to pay attention in followings:

1. Do not overlap when layout double-side BGA and a certain of distance is required left. The reason why to do that as it is difficult to repair if there is poor BGA on one of sides.

2. In order to prevent the BGA on the bottom from melting during the second time reflowing, it is required to decrease the bottom temperature in the second time reflowing. It is better to decrease the bottom temperature lower than to the melting temperature of solder joints to ensure that the solder joints do not melt again. What’s more, you can fix the bottom BGA with jig.

4 ways to increase deformation resistance for flex circuits:

1. The stress resistance of BGA can be strengthened by a supporting iron frame around it.

2. The stress resistance of BGA can be strengthened by gluing around it or on the corresponding back of flexible PCB.

3. If you aim at protecting the BGA, then you are able to add screw to fix the other parts around BGA. In this way, the other parts around BGA won’t deform easily.

4. Strengthening the outer shell of flex circuits to avoid its deformation affecting the inner circuit.

How to Paste Coverlay on FPC?

If you have ever learned something about flex circuits, you would know there is a layer of coverlay on it. Pasting coverlay on flexible circuit is to prevent it from the damages of dust, moisture and so on. Meanwhile, it also plays an role in insulation. We have learned something about the benefits of pasting coverlay on flex circuits, but how to paste the coverlay? Let’s take a look.
To begin with, we need to prepare the coverlay material, checking whether the soldering iron has power, cleaning the residue of soldering iron and the dust-free paper.

The procedures of pasting the coverlay on FPC:

  1. Checking whether the coverlay and film have problems, including missing punching, missing drilling, too large burr on the coverlay etc.. After that, clean the dust on the surface of coverlay with packaging cleaner.
  2. Cleaning the worktable and putting the coverlay, soldering iron and other tools in the right place.
  3. Checking whether there are oxidization, litter, dust etc. on the flex circuits to be pasted.
  4. Pasting the coverlay should follow the requirements of process and the MI data. It should be strictly follow the “C”marking line, pad or counterpoint hole when align.
  5. How to peel the coverlay off: putting the covelay on the optical desk, but please remember that the release film is facing up and the coverlay is facing down. After that, holding the coverlay then peeling off the release film slowly.

  1. Fixing the coverlay on FPCwith soldering iron after the coverlay is aligned with the “C” marking line of the flex circuit board and ensure it is correct, so that the coverlay can not deviate or peel off. However, please remember the soldering iron can not burn the products.

  1. Single-side lamination: after pasted the coverlay on FPC, it should be gone through the machine with temperature between 160°C-165°C. Next, until the board got cold, the release film should be peel off and carry out the single-side lamination and self-checking.

Notices:
1. It is necessary to wear rubber gloves to prevent the flexible printed circuit board from oxidization or dirty.

  1. It must be kept clean during pasting coverlay on FPCto prevent there are dirty residues on flex circuits.
  2. It is required to check whether the coverlay is broken, wrinkled, scratched, etc..
  3. Do not wear accessories to avoid scratching the board.
  4. It is necessary to confirm that the coverlay leave a little bit space for plating if the flex circuitsare tin or gold plating.
  5. The hand could not beyond the handle to avoid burning when holding the soldering iron.

The Keys in the Mobile Phone

With the development of smart phone, the mechanical key has been already eliminated from the stage. There is only the HOME key left on the front side of the phone. Even sometimes the HOME key is also out and there are only two keys left–volume key and power key. These two are usually used a FPC to save cost as well as space. The structure showing as below:

volume key & FPC

power key & FPC

For the design of volume key and power key, there are two things required to considerate. On one hand, the position of the flex circuit. Since the flexible circuit is glued on the supported wall, three directions need to be limited if you would like to fix the FPC. As well, the designers still need to consider the installation position of the keys itself, which determines the basic structure of the keys.

On the other hand, the volume key and power key are moving parts. Therefore, taking the stroke of metal domes into account is necessary and as general rule the stroke is 0.3. In addition to hard contact mode, there is also a soft contact mode (P+R), which is to use rubber or TPU (Thermoplastic polyurethanes) for the part where the key is contact with the dome, so that the sound is softer.

Flexible Screen-Another breakthrough for FPC

Royole Corporation released the first foldable flexible screen mobile phone (FlexPai) last month in the world. Its release perfectly figures out the long-term contradiction between HD large screen and portability. Meanwhile, it created a new way of human-computer interaction.

Actually, in addition to mobile phones, flexible screens are widely applied in smart home. The televisions with curved surface screen are no wonder to everyone, but most of people will keep an eye on flexible screens. If the flexible screen can be used in display devices of smart home, the display devices will have more affinity in human-computer interaction.

Think about it, there are many interactive displays that can be turned on and off at any time, everywhere. Then your home will seems like the scene in science fiction movies. But if we would like to realize the flexibility of the screens, flex circuits must be used in the designing. Because as the name implied, the flexible circuits possess the benefit of high flexibility which make them can be folded at your will.

New Product–2L FPC Coil Board with Bumped Point

  In September, 2018, in order to provide customers with the most suitable products and the most satisfactory services, Best Technology released a new product—-2L FPC Coil Board with Bumped Point. This product was developed on the basis of the old version. The surface of the old one is flat. For this reason, it will cause poor contact when assemble with a conductive film.  

  Could you tell the difference between the old one and the new one? If not, hoping this article can solve your puzzle.

New Version VS Old Version

Picture1: New Version VS Old Version

  There is an obvious difference—-the new version has bumped point, but the old one is opposite. So what is the advantage of 2L FPC Coil Board with Bumped Point? The new one with bumped point, it will get easier to connect when assemble with a conductive film. Because the shortcoming of the old one, we have improved with advanced technology, adding bumped points in the flex printed board. And it is easier to connect when the pad is attached with the conductive film.

  From the following picture, we can see that the new version is single-sided flexible circuit board with bumped point.
