What are the advantages of multi-layer PCBS over regular PCBS

PCB 為我們社會中的許多行業和設備提供動力。 As our technology evolves, so does the demand for different types of PCBs. When you choose between single-layer and multi-layer PCBs, the options seem endless. 在購買新 PCB 之前,了解每個選項的優缺點很重要。 These are some of the benefits of buying multilayer PCB on a single-layer design.

PCB

First, it’s important to understand what a multilayer PCB is and how to make it.

A single-layer PCB having a layer of conductive material. 您會發現安裝在電路板一側的導電接線圖和安裝在另一側的組件。 單層PCB常用於簡單的設備中,因為沒有電線交叉使電路正常工作。 雙面PCB類似,功能比單層板多,但比多層PCB少。 它們的每一側只有一個介電層和一個導電金屬層。

另一方面,多層板比單層或雙面 PCB 更複雜。 Multilayer PCB has three or more layers of conductive material. 其他層,通常是銅箔,堆疊在芯的頂部。

Start with the core. 此後添加的每一層都沒有完全固化。 In this way, the manufacturer can adjust them relative to the core. 之後,箔繼續向前,並可以通過層壓過程與其他層交替。 必須使用壓力和高溫技術來組合各層並將它們安全地融合在一起。

單層和多層PCB

多層 PCBS 有很多好處。 總的來說,這些板更小更輕,這使得它們非常適合智能手機或電腦,或其他需要多功能包裝的產品。 Here are some special benefits:

多層 PCB 讓您獲得更多功能。

高組裝密度意味著您可以延長電路板的使用壽命。

當您不需要多個獨立 PCBS 的連接器時,結構更簡單。

LA 在製造階段的嚴格測試流程意味著您將獲得高質量、高效的產品。

The electrical characteristics of multi-layer PCBS are faster than single-layer boards.

L 根據您選擇添加的層數,多層 PCBS 通常適用於剛性和柔性結構。

相比之下,雖然單層 PCBS 在某些應用中很有用,但它們也有一些不容忽視的缺點。 以下是單層的一些缺點:

由於電線不能交叉,單層板是簡單電子產品的理想選擇,並且在使用中沒有太多的通用性。

L 儘管單層 PCBS 的製造成本較低,但它們的使用壽命不如多層 PCBS,這意味著它們的總體成本效益較低。

單層 PCBS 無法達到多層 PCBS 的速度。

L Circuit boards that have a single layer are limited to their circuit design because they have only one conductor and each line requires its own path.

Although single-layer PCBS is an acceptable choice for low-density designs, the characteristics of multi-layer PCBS make them the best choice for many industries looking for a more durable and versatile option.

多層PCB的使用

Many industries and products can benefit from multi-layer PCBS, especially because of their durability, functionality, and lightness. Here are some products that often use these boards:

l 電腦

L Heart monitor

升火

LGPS and satellite systems

L Industrial control
