Talk Something about Multilayer PCB

Description

Days ago, one of our customer sent us an e-mail and asked something about multilayer PCB and many customers will send us e-mail in order to get the stack-up of our multilayer PCB. And we upload this passage with the hope of helping our customers to have a brief idea of <a href="https://www.allpcb.com/pcb_layer_stack-up.html" target="_blank">multilayer PCB</a> in ALLPCB.  What is Mutilayer PCB? Multilayer PCB is a printed circuit board that has more than two layers copper. All multilayer PCBs must have at least three layers of conductive material. Please kindly check the stack-up: <div style="text-align:center;"> <img src="https://file.allpcb.com/bbs/19/01/04/154041729.png" alt="4 layer lay up(thickness 80mil)" /> </div> <img src="https://file.allpcb.com/bbs/19/01/04/154124255.png" alt="4 layer lay up(thickness 63mil)" /> <div style="text-align:center;"> <img src="https://file.allpcb.com/bbs/19/01/04/154143331.png" alt="4 layer lay up(thickness 47mil)" /> </div> <img src="https://file.allpcb.com/bbs/19/01/04/154442826.png" alt="4 layer lay up(thickness 39.4mil)" /> <img src="https://file.allpcb.com/bbs/19/01/04/154506200.png" alt="6 layer lay up(thickness 63mil)" /> <img src="https://file.allpcb.com/bbs/19/01/04/154527004.png" alt="6 layer lay up(thickness 79mil)" /> And you can take above stack-up data as reference if you want to design a multilayer PCB. Benefits of Multilayer PCBs 1. Powerful functions. Of course the multilayer PCBs can do something that one or two layer boards can’t. Cellphones, GPS technology, Space probe equipment and so on. They all require multilayer PCBs. 2. Multilayer PCBs provide high capacity and high speed in a smaller footprint. 3. Multilayer PCBs can be produced in both rigid and flexible boards 4. Save space and reduce weight when assemble. Because they are generally smaller than one or two layer boards. When you assemble the PCBs, they can save you a lot of space, as well as reduce the whole weight of your whole works. Applications With the development of the technology, multilayer PCBs are widely used in many high-tech fields. And multilayer PCBs are especially widely used in professional equipment(space and military fields). Below are some other applications of multilayer PCBs. 1. Cellphones 2. GPS technology 3. Computers 4. Data storage technology 5. X-ray equipment 6. Heart monitors 7. Scan technology 8. Space probe equipment 9. Cellular transmitters  How To Order Multilayer PCBs From ALLPCB? As you can see in our instant quote, now we have 4 and 6 layer in <a href="https://www.allpcb.com/" target="_blank">our website</a>, you can order directly in the website, please kindly noted that you should fulfill “layer orders” before you add the order into your cart. If you have boards with more than 6 layers, please kindly send the requirement with the gerber file to service@allpcb.com, and we will reply you within 24 hours.  <div style="white-space:nowrap;"> </div>
