PCB panelization is one of the most effective methods for mass production of small circuit boards. By improving efficiency, it is possible to reduce costs, shorten manufacturing time, and make it easier to use printed circuit board manufacturing equipment.

PCB panelization is the process of manufacturing small circuit boards as part of a wider array. The reason for the existence of this technology is that many production machines are unable to handle circuit boards below a specific size. Put the boards together and then separate them along the predetermined fault line to solve this problem.

If you want to try panel PCB components, please remember the following PCB panel guide.

The advantages of PCB panelization

The most significant advantage of PCB panels is high mass production efficiency, reduced vibration and vibration, improved product safety and cost-effectiveness. Most manufacturers strongly prefer to use standard sized processing panels, so creating arrays of the same size can greatly reduce production costs.

Important factors to consider when panel PCB

design

The design requirements of the product vary greatly, including significant limitations on the size of the internal circuit board. Some boards also have unusual shapes, such as curves, rather than simple popular rectangles. Panel processing of PCB components can reduce wasted panel space and design panels to meet your needs, rather than production requirements.

component

Components are a fundamental consideration for all printed circuit boards, but the use of panels can provide more material options. The small board is weak and prone to vibration and impact, so it usually requires the use of stronger and more robust components to withstand vibration.

Use the absolute size of the panel to minimize impact and shock, so you can use lower priced parts without damaging the integrity of the circuit board.

How big is the PCB panel? The production scale varies, but most companies use the 24 inch standard and 18 inch standard. PCB panel size.

Ingredients

Materials are often confused with components. Usually, components are parts placed on a circuit board, and the material covers the circuit board itself. In most cases, panels enable you to use more affordable materials. By reducing waste in the production process, these costs have been further saved.

PCB assembly method

V score panelization

What is the V-slot in PCB? The V-scratch splicing plate is sometimes referred to as a V-shaped cutting groove, which involves removing the V-shaped portion along the top and bottom of the panel. The depth of the groove varies, but most incisions occupy half of both sides, making it easy to cut in the future.

The circuit board is stronger than many people imagine, so the rest needs to be disassembled by the machine.

Design considerations

clearance

The gap from the component to the center of the groove is 0.05 inches. It may be necessary to place higher components further away to make room for the cutting machine to operate.

Jump score

Jump score refers to the process of not obtaining a v score on the entire panel. In most cases, manufacturers will do this to fully maintain the integrity of the waste track (unprinted edges of the circuit board) during the production process. Scores that cannot jump may damage the array during the production process, so it is best to leave approximately half an inch at the end of each panel.

Label routing panelization

What is label routing? The key to label wiring panelization is cutting, while leaving perforated labels that can be eliminated or cut during the production process.

Design considerations

surface stress. The weakness of the array is a potential major issue, so you must ensure that you purchase sturdy boards.

knockout stage

Most tab panels use a five hole remover whenever possible. If it fails, 3D mode can also be used, but it must be tightly placed together to ensure the integrity of the overall structure. The three hole pattern is also very useful when the convex piece needs to be placed under other components.

Label position

Labels should be kept as far away from other components as possible. This may cause some difficulties in the design process, but the increased pressure may damage nearby components, so limiting production is crucial for creating long-lasting products.

Perforation placement

Perforations should be placed on one or both sides of the label, rather than directly passing through the middle of the label. The main reason for doing so is to minimize the protrusion size of the lugs, ultimately helping to improve the integrity of the printed circuit board.

array arrangement

Array layout should minimize the use of labels and movement as much as possible. Fundamentally speaking, PCB splicing can be better completed with less processing, so the fewer channels that the cutting machine needs to produce, the better. With the correct panel, almost all available space on each PCB board can be used for circuit boards.

Solid tab panelization

Solid tab panelization is an alternative method to previous options, where each panel contains relatively large solid tabs between them. This is not very popular because cutting thick labels in the future will be difficult and expensive, but it does provide better structural integrity in the manufacturing process.

Breakthrough PCB board

Break the label with your hands

You can break the protruding tongue on the PCB panel with your hand, but this is usually a bad choice unless the circuit board is thin and designed for this purpose. Humans may apply pressure in different areas where wooden boards are damaged, which could render them unusable in the future. Some people use hook devices to cut protruding ears, even though they are easy to move back and forth.

Using machines to break labels

Using machines to break labels is usually more effective than using hands to break labels. Machines can damage panels by fixing them and using blades, or by cutting panels with lasers and other more advanced tools.

Break the V-shaped groove with your hand

V-shaped grooves are easier to break by hand than protruding ears, especially because pre-existing incisions are weak points that usually break before anything else.

Cutting V-shaped groove

Cutting V-grooves with a saw blade (imagine a pizza knife) is usually more effective than manual cutting. Some people use machines, such as distribution board slot machines, which can accurately cut slots without applying too much pressure to other parts of the panel. Hiring a suitable manufacturer can ensure that you receive cut wooden boards.
