When investing in an SMD screen, it’s crucial to keep several factors in mind:

1. Screen Size and Resolution

The size and resolution of the screen are fundamental. Determine the screen size based on your intended use, and opt for a resolution that ensures clarity, especially if you plan to display intricate visuals.

2. Display Technology

There are different types of SMD screens, such as LED, OLED, and QLED. Each has its advantages and disadvantages. Choose the one that best suits your requirements.

3. Budget

Your budget plays a vital role in your choice. Digital Innovation SMD, based in Lahore, offers competitive pricing without compromising on quality. This makes them an excellent choice for those looking for cost-effective solutions.

4. Durability

SMD screens should withstand various environmental conditions, so look for screens designed for durability and longevity.

5. Color Accuracy

For applications where color accuracy is crucial, ensure the smd screen you choose offers accurate and vibrant colors.

6. Connectivity Options

Consider the types of ports and connectivity options available, as they can greatly impact compatibility with your existing devices.

7. Warranty and After-Sale Service

Digital Innovation SMD is renowned for its excellent after-sale service and warranty, ensuring your peace of mind post-purchase.

Tips for SMD soldering

Soldering can be done with through-hole components as well as with SMD. SMD is more and more common because the components are much smaller. This results in more efficient printed circuit boards with more parts per surface area. However, SMD soldering is a specialty and several things are different from through-hole. This article is meant to give an introduction to soldering SMD compendiums and it is assumed that the article about handsoldering has already been read.

What is SMD?

SMD components are very small "Surface-Mounted Devices". This term covers virtually all components that are not through-hole. From resistors to LEDs to complete Integrated Circuits (ICs). These components have various standard sizes and layouts. This is important to keep an eye on because of the associated footprint. The dimensions of simple SMD components are displayed in 4-digit codes that describe length and width dimensions in inches. This makes it easy to see how large the components are.

The soldering station is of course the most important part when soldering SMD components. It is important to choose a good tip. This is more important than a good soldering station because even our JBC stations cannot be used properly with a wrong tip. When choosing the tip, it is important to take one that matches the size of the SMD components used. These components have a certain width of the pads and are therefore easier to solder with a tip that fits the size of the pads. Our advice is to choose a chisel-shaped tip between 1 and 2 mm. These are very suitable for heat transfer because of the shape.

Soldering tin and flux

The choice of solder depends on your application, if you are going to perform repairs on existing electronics it is more convenient to take lead-free solder. This is because the solder present on printed circuit boards today is almost always lead-free for environmental reasons. Lead-containing and lead-free solder do not mix, and if you want to work with lead-containing solder, the pad will have to be cleaned completely. If you want to build your own PCBs, you can use either lead-free or lead-containing, in which case only personal preference is important. It is also possible to use solder paste instead of tin, but this is almost exclusively used with reflow or hot air.

Flux is essential to make soldering easy. By rubbing the pads of your print with flux, the solder will automatically flow to the right place. This makes it very easy to solder without soldering IC pins to each other.

Other useful tools

These tools are very useful, because SMD soldering with the fingers and the naked eye is a lot more difficult than with tools. For example, it is useful to use a third hand with magnifying glass, as you will quickly run out of hands when soldering. In addition, you will notice that the larger the magnification, the more stable your hands become. So it might also be an idea to create a loose magnifier or a microscope to consider working properly. Furthermore, tweezers are indispensable to place smd components. To remove excess flux from the print, Isopropanol alcohol is a good option.

SMD soldering

The soldering process takes place in a number of steps that can follow each other quickly in practice. It is very important that the tip of the soldering iron is clean.

1. Tin one of the pads to make sure that the component can be placed. The pad should be fully tinned but be careful not to overdo it. 2. Place the component in the right place while keeping the solder liquid. A pair of tweezers is essential for this. It is important that the placement of the component is fairly good, otherwise the second pad will be difficult to get right. 3. Lubricate some flux on the other pad.
4. Provide the tip with a good amount of solder.
5. Touch the pad with the tip, the solder will automatically flow into the pad and form a nice solder joint. 6. Inspect the solder connection and clean if it is cool, possibly the flux away with Isopropanol alcohol. This does not necessarily have to be done, but gives a more finished result. If there is too much solder on a joint, the easiest way to remove it is with a little desoldering tape.

ICs soldering

These steps are very similar to the above, ICs are only a bit more difficult because they have a lot more connectors on a smaller area. This makes soldering a lot more precise.

1. Distribute flux over all pads. Tin one of the pads with a good amount of solder. 3. Place the IC in the right place while keeping the solder liquid. A pair of tweezers is essential for this. It is important that the placement of the component is fairly good, otherwise the other pads cannot be soldered properly. 4. Solder the rest of the pads. The flow of the solder should be automatic, otherwise more solder should be added. Inspect the solder connection and clean it when it is cool if necessary the flux away with Isopropanol alcohol. This does not necessarily have to be done, but gives a more finished result. If there is too much solder on a joint it is easiest to remove with a little desoldering tape.

Soldering rules

1. Inside outwards. The most convenient order to work is from the center of the board to the edges. For different component sizes, the easiest way to work is from small to large. 2. Keep the pad cold. If a path on a circuit board gets too hot, it is possible that it will let go. Then it is possible that the whole PCB can go away, if it was an important part. This can be done by simply not soldering for too long in one place. If it doesn't work out, try again later. 3. Keep the tip clean. The soldering tip must be kept very clean when soldering with SMD. This promotes dissipation and heat dissipation. Oxidized soldering tin is a poor conductor, which also contaminates the soldering to be made. This is why the soldering tip must be cleaned for each series of soldering operations. The sponge must be moist, but not really wet. Otherwise the temperature of the tip will drop too much.

Furthermore, the rules mentioned in the handsoldering article also apply here.

With this information you can make a start in the world of SMD soldering. For hobbyists this can provide enough information to solder PCBs, but the most important thing with soldering is practice. Without practice, the solder joints never get better.

To conclude, a word of thanks to Marc van Stralen for the source on which this article is based.
