Multilayer circuit cards, or multilayered PCB boards, are used to electrically connect components, also known as traces. With a reputation for reliability, multilayer circuit card manufacturing is in high demand in the telecommunication, computer and automotive industries. Multilayer PCB fabrication is also in demand in high-tech industrial equipment manufacturing processes.

The growth of the multilayer circuit boards business has increased in response to demands by manufacturers to make electronics products that are small in size yet high in performance. Without multilayer PCB fabrication, manufacturers would be forced to increase product size in order to improve device performance. Consider the following when selecting a multilayer PCB manufacturer:

1. Narrow down your list using a trade directory that includes names of multilayer PCB manufacturers.

2. Compare competitor prices for multilayer circuit cards using manufacturer websites.

3. Choose a PCB board manufacturer with appropriate credentials for your industry.

Action Steps
The best contacts and resources to help you get it done

Find names of multilayer PCB manufacturers using trade directory websites

There are many companies worldwide that manufacture multilayer printed circuit boards, also referred to in catalogs and websites as PCBs.

I recommend: Global Sources, a service provided by Trade Media, lists almost 2,000 multilayer PCB manufacturing companies that export worldwide. TradeKey also lists multilayer PCB manufacturers.

Compare competitor prices for multilayer circuit boards.

Competitor prices for multilayer PCB boards vary according to the amount of layers you select, as well as the size of the circuit board order you place. Oftentimes the cost per unit will decrease if you place a high volume order.

I recommend: Quick Turn Circuits sells multilayer circuit boards and guarantees a 48-hour turnaround time. Just complete their form and they will get back to you with a price quote. Imagineering's website allows you to select up to 10-layered custom-made multilayer PCB boards. Their user friendly form is easy to complete and will provide you with an instant price quote.

Make sure your PCB board manufacturer has attained the appropriate credentials

There are many credentials and certifications associated with multilayer circuit boards manufacturing. Depending on the business you come from and the industry for which the PCB board will be made, anything you order should come from a provider with the appropriate certification(s).

I recommend: Saline Lectronics is ISO 9001:2000 and AS9100:2001 certified for the aerospace industry, ISO 13485:2003 certified for medical board production and even ITAR registered for sensitive military and intelligence applications. Lastly, they are RoHS compliant. The Washington State facility for Prototron Circuits was certified to ISO 9001:2000 in 2003. They also manufacture RoHS compliant boards by request.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Many multilayer PCB manufacturers promise quick turnaround time from the point of order to the time of delivery. Depending on the company, this time can be anywhere from 24-48 hours. The length of time is generally impacted by the number of layers your multilayer circuit board will require.
