By using the circuit board, the lighting companies can now device low heat dissipating, duster and moisture resistant, and low profile LED lights that are applicable in all spectrum of life. To go around this as a designer or even final user, you might need to find a custom led circuit board to power up your LEDs.

However, even with innovation, there are still loads of problems that undermine the LED lights' efficiency. Here are seven solutions for LED lighting PCB assembly that you need to look out for in any system.

1.Control current

LED light, the soul of lighting globally, enjoy merits such as high illumination, long lifetime, stability, and low energy consumption. That is why the technology has wiped out some other contemporary lighting methods, such as halogen and fluorescent tubings.

But even with the merits, the technology came with one disadvantage that undermines its efficiency a great deal&#;a custom led circuit board tends to generate high heat energy. Thus, the system cannot cool efficiently through traditional means.

The custom LED PCB assembly uses metal core PCBs due to their high efficiency when it comes to problems related to heat dissipation. Some other companies use aluminum PCB. The metals have thermally conductive dielectric materials that conduct heat with unmanageably higher efficiency while at the same time dissipating heat.

When your lighting system emits large amounts of energy, you risk damaging the connected accessories. For example, LED lights in the aquarium tanks will emit heat to your waters hence causing pets to boil. PCB assembly caulks all these problems to make LED lighting technology flawless.

2. Welding LED Components

Among the things that one needs to take proper control or care of when doing PCB assembly are the welding components. For an LED light to work effectively and be as durable as they need to be, one must ensure that they welded on the right base. A ceramic plate is the most effective because it will minimize heating. A ceramic base is ideal because it will ensure durability and strength to the custom LED PCB.

When you are doing PCB assembly, there are some matters that you need to take into proper consideration. These are:

I.The solder bridge: when there is an unpredicted connection when you are soldering, it might lead to shorts circuits. You should, therefore, be careful when making any soldering connections.

II. Lifted components can also happen when you are soldering, so the manufacturer needs to be careful at all times.

III. Keep the soldering bit clean and neat so that you can get a proper joint, and this will also make you have adequate heat induction when soldering.

IV. Start with soldering the small parts and then move on to the more significant elements. Hence, it will make it easy for you to assemble the PCB.

3.Material Selection of LED PCB Board

Generally, the functionality, manufacturability, and life cycle of PCBs make LED lights rely on its construction. Therefore, the list of materials you chose for your board can either bury or enhance the whole system's quality and efficiency.

To develop an all-time efficient board, PCB manufacturers use a wide assortment of products ranging from substrates and laminates to Circuit Board Types. However, it is worth noting that only one material wrongly placed in the PCB can ruin the board's overall functionality. That is why material selection remains a significant problem in the LED PCB assembly.

So, what is the way forward? The best solution is to enlist flex, rigid, and customized boards from well- renowned manufacturers so that you can come up with a better board. And WellPCB is one of them. You can also acquire the already made parts and conjoin them together to form the PCB assembly boards.

Typically, the board consists of a series of layers that overlap each other. You can acquire the layers separately and join them together to get moving.

Focus on coming up with a thicker board. A thicker board will guarantee significant support to the connected devices with negligible risks of failure. A standard thick board usually is 1.6 mm. Anything less than that can compromise your PCB assembly's durability, quality, and functionality in totality.

How to Wire Multiple LEDs on a Circuit Board

If you want to wire multiple LEDs on a circuit board, you do so through parallel wiring. When you are wiring LEDs in parallel, you're simply creating different mini circuits with each having their own power supply. Every circuit contains of the battery, a LED and a resistor.

How to Solder LEDs to a Circuit Board

Here are the steps to follow on how to solder LEDs to a circuit board as below:

1. Tinning the tip: For you to solder, you have to use a tinned tip. In order for you to properly tin the tip of an iron, you have to apply solder to the tip and then make sure that you coat it thick. Afterwards, you should wipe the extra solder with a wet material and then reapply a small quantity of solder to the tip once again.

   
   

2. Ensure that the solder surface is clean: The surface has to be clean for it to have quality results. Thus, ensure that you take away any dust, dirt, or any element that's on the surface. Learn more details about how to clean the pcb here.

   
   

3. Tin the surfaces: Before the final connection is done, the wires should be tinned. Apply a thin layer of solder on the wires. Ensure that the solder sticks to the wire. Next ensure that the solder pad is tinned too. Apply solder to the pad. The solder has to flow evenly on the entire pad. Afterwards, take the iron away and allow the solder to firm up.

   
   

4. The Final connection: Use a tinned tip and surface to hold the two pieces being soldered with the iron. The solder on each surface has to flow. Remove the iron quickly and after the solder hardens, both components should be soldered.

It's imperative to take note that soldering can be difficult, especially if you've never done it before. It is possible for you to damage a component. The important thing to remember is that irons are hot and LEDs don't like exposure to a lot of heat. So, you have to be extremely cautious with the temperature setting on your iron and the amount of time you use to apply the iron on the surface. It should take a few seconds for solder to flow and attach itself on a surface.
