How Do You Fabricate An LED Strip PCB?

The steps that you will take when manufacturing an LED strip PCB include the following:

Preparação de Material

In this phase, you will prepare the components and the printed circuit board and ensure they have no flaws.

The printed circuit board is flat and has copper pads without holes, also known as solder pads.

Preparação do estêncil

The stencil provides a stationary position enabling you to perform solder paste printing.

Also, the production process occurs in line with the solder pad design position on the circuit board.

Impressão de pasta de solda

In this phase, you use a solder paste to connect all components and solder pads on the printed circuit board.

The solder paste is usually a mixture of tin and flux.

Posicionamento de componente

The printed circuit board containing the print goes to the pick-and-place machine.

A conveyor system will relay them and you will proceed to place all the electronic parts accurately on the board.

Soldadura por refluxo

The printed circuit board moves to the reflow soldering oven after you finish placing the components successfully.

Here, the board moves within a pre-heat area in the oven where the temperature of the circuit board and components increases gradually.

After that, it moves into the soak area where you maintain a steady temperature for a specific time.

Afterward, the reflow area allows the tin on the solder paste to melt thereby improving bonding on the LED strip PCB.

The final step involves cooling the solder thereby preventing defects on the joints.

Inspeção

This is the final phase that entails cleaning and repairing any flaws on the LED strip PCB before storage and shipping.

Is It Possible To Repair An LED Strip PCB?

Here are the steps to fixing an LED strip PCB:

Securing The PCB

Once you know that there is a flaw with the LED strip PCB, secure the board before beginning the operation.

Use a hot gun glue close to the faulty component for a few seconds then use tweezers to remove the faulty component.

Limpeza

Once you remove the faulty pad or component, use a sharp knife, sharp-pointed screwdriver, or fine-grit sandpaper to eliminate any solder.

This allows you to fully expose the track, which appears clean and shiny.

Placing Copper Tape On The Track

Here, you will place copper adhesive tape on the area you just cleaned.

The tape should overlap the track and completely cover any thru-hole and part of the surrounding area.

Joint Soldering

This step entails soldering the joints carefully on the area that the copper tape attaches to the track on the LED strip PCB.

Some tips and warnings regarding this process entail the following:

  1. At soldering temperatures, the copper tape will melt rapidly thus only start when you are sure you can complete this process in a single run.
  2. Quickly apply minimal heat to lower the amount of heat that you apply on the board.

Restoring Thru-hole

Use another tool to press on the area after soldering and rub it to ensure a secure hold of the copper tape on the whole area pad.

In this phase, once you detect the area where a through-hole exists, use a small and sharp pin to punch a hole.

Component Placing And Soldering

After performing the tasks above, the LED strip PCB will be ready to receive the component replacement of choice.

Ensure the heating phase is as brief as possible since the new joint between the copper and track may be fragile.

Trim Surplus Tape

Here, you will use a craft knife or scissors to trim excess copper tape to the size of the final finish repair.

Besides, the joint may restore the functionality of the LED strip PCB, but the pads, joints, and tracks may not be structurally sound.
