Višeslojni PCB has gained great popularity in various industries. Danas je lako pronaći nekoliko vrsta višeslojnih PCBS-a, uključujući 4-slojnu PCB, 6-slojnu PCB, itd. Six-layer PCBS have become an integral part of compact wearables and other mission-critical communications devices. What makes them popular? How are they different from other types of multi-layer PCBS? Ovaj post je dizajniran da odgovori na sve informacije koje želite znati o proizvođaču 6-slojnih PCB-a.

Introduction to 6-layer PCB

Kao što naziv implicira, šestoslojna PCB ploča sastoji se od šest slojeva vodljivog materijala. It’s basically a 4-layer PCB with two additional signal layers placed between the two planes. Tipična šestoslojna ploča sa PCB-om ima sljedećih šest slojeva: dva unutrašnja sloja, dva vanjska sloja i dvije unutrašnje ravni-jedan za napajanje i jedan za uzemljenje. Ovaj dizajn poboljšava EMI i pruža bolje usmjeravanje za signale niske i velike brzine. Two surface layers help route low-speed signals, while two internal buried layers help route high-speed signals.

The typical design of a 6-layer PCB is shown above; However, it may not be suitable for all applications. The next section highlights some possible configurations of 6-layer PCBS.

Key considerations when designing 6-layer PCBS for different applications

Properly stacked 6 layers PCB manufacturers can help you achieve better performance because it will help suppress EMI, use various types of RF devices as well as include several fine-pitch components. Any errors in the lamination design can seriously affect PCB performance. Gde da započnem? This is how you stack properly.

L Kao prvi korak u kaskadnom dizajnu, važno je analizirati i riješiti broj uzemljenja, napajanja i signalnih ravnina koje bi PCB -u mogle biti potrebne.

L grounding layers are an important part of any lamination because they provide better shielding for your PCB. Moreover, they minimize the need for external shielding tanks.

Evo nekoliko provjerenih 6-slojnih dizajna PCB-a za različite primjene:

L For compact panels with small footprint: If you intend to wire compact panels with small footprint, four signal planes, one ground plane and one power plane can be installed.

L For more dense boards that will use a wireless/analog signal mix: on this type of board, you can choose layers that look like this: signal layer/ground/power layer/ground/signal layer/ground layer. In this type of stack, the internal and external signal layers are separated by two encapsulated ground layers. Ovaj slojeviti dizajn pomaže pri suzbijanju miješanja EMI -a s unutrašnjim slojem signala. The stack design is also ideal for RF devices because ac power and grounding provide excellent decoupling.

L For PCB with sensitive wiring: If you want to build PCB with many sensitive wiring, it is best to choose a layer that looks like this: signal layer/power layer / 2 signal layer/ground/signal layer. This stack will provide excellent protection for sensitive traces. The stack is suitable for circuits that utilize high frequency analog signals or high speed digital signals. Ovi signali će biti izolirani od vanjskih signala male brzine. This shielding is done by an inner layer, which also allows routing of signals with different frequencies or switching speeds.

L Za ploče koje će biti postavljene u blizini jakih izvora zračenja: za ovu vrstu ploča uzemljenje/signalni sloj/snaga/uzemljenje/signalni sloj/uzemljenje će biti savršeno. This stack can effectively suppress EMI. This lamination is also suitable for boards used in noisy environments.

Benefits of using 6-layer PCBS

Thanks to the six-layer PCB design, they have become a regular feature in several advanced electronic circuits. These boards offer the following advantages that make them popular with electronics manufacturers.

Mali otisak: Ove tiskane ploče manje su od ostalih ploča zbog svog višeslojnog dizajna. This is especially beneficial for micro devices.

Quality driven design: As mentioned earlier, a 6-layer PCB stack design requires a lot of planning. This helps reduce errors in detail, thus ensuring a high-quality build. In addition, all major PCB manufacturers today employ various testing and inspection techniques to ensure the suitability of these boards.

Lightweight construction: Compact PCBS are achieved by using lightweight components that help reduce the overall weight of the PCB. Unlike single-layer or double-layer PCBS, six-layer boards do not require multiple connectors to interconnect components.

L Improved durability: As shown above, these PCBS use multiple insulating layers between circuits and these layers are bonded using protective materials and different prepreg adhesives. This helps improve the durability of these PCBS.

L Excellent electrical performance: These printed circuit boards have excellent electrical performance to ensure high speed and high capacity in compact designs.
