• Ứng suất cơ học: The cutting action can induce some ứng suất cơ học, which can damage các thành phần nhạy cảm.
• Tốc độ: Slower compared to some of the more advanced methods.

I’ve seen lộ trình work wonders in high volume setups that have lots of boards of a similar shape and size. The bộ định tuyến head is moved using computer controls and very little operator interaction is needed. This makes it very repeatable and reliable.

V-Groove Depaneling: Simplicity and Speed

Rãnh chữ V depaneling stands out for its simplicity. A V-shaped groove or điểm v is cut into the panel along the separation lines, and the pcb cá nhân are then broken apart. This process is ideal for panels designed with straight lines of separation between the individual circuits.

Pros:

• Tốc độ: It is a very fast separation process.
• Low Cost: It is an economical method for designs suited for it.
• Simple: It is an easy method to learn and implement.

Cons:

• Design Limitations: Only works with straight-line separations.
• Potential for Rough Edges: Can create rough edges which sometimes require additional cleanup.
• Ứng suất cơ học: Breaking the panels can cause stress which can affect the integrity of the hàn and the connections.

I’ve witnessed Rãnh chữ V depaneling excel in environments where there are individual printed circuit boards arranged in a grid format. The straight lines and high-speed separation process is a match for thông lượng cao lines. However, when the designs get more complex, this solution is not a match.

PCB Punching: Speed at the Cost of Flexibility

đấm is another mechanical method that is used to cut the pcb cá nhân from the larger panel. đấm requires the creation of a die, which is created for each unique pcb shape. This process is fast but the requirement for the die is very limiting.

Pros:

• High Speed: Very fast separation for large panels.

• Ứng suất cơ học: The punching process can create a lot of ứng suất cơ học to the components on the edge of the board.

I’ve seen this type of method used when the designs are relatively simple and the production numbers are very large. For instance, if there are just a handful of parts on the pcb, then the đấm process can make a lot of sense. It’s a good solution for simple shapes but it quickly becomes unsuitable if the shapes are more complex.

Laser Depaneling: Tương lai của sự chính xác

Tháo gỡ bằng laser is the most modern quá trình tách biệt and is accomplished by using a focused tia laze beam. The tia laze beam is used to remove the pcb material.

• Tốc độ: It can be slower when compared to some of the other processes but this can depend on a few factors.
• Setup: It can take some time to configure, especially when a lot of different shapes or types of pcbs are being created on the same line.

I’ve seen tách tấm bằng laser implemented in a lot of sản xuất pcb environments that create flex pcbs and also smaller rigid pcbs. It’s truly one of the most exciting technologies in modern sản xuất pcb. It allows the creation of very complex designs and it is ideal for situations where ứng suất cơ học is a concern.

Automation: Boosting Efficiency and Precision

The incorporation of automation in the quá trình tháo dỡ significantly boosts efficiency and reduces human error. Automation can take the form of an tách bảng nội tuyến system that handles the quá trình tách biệt and passes the pcb cá nhân directly into the next stage of the dây chuyền sản xuất. There are also systems that simply collect the boards for removal at a later time.

Pros:

• Tăng thông lượng: Automated systems can increase production line speed and reduce costs.
• Sự nhất quán: Provides highly consistent results, with every board being processed identically.
• Giảm thiểu lỗi của con người: Automated processes eliminate mistakes caused by operator error.
