Rocket PCB manufactures aluminum printed circuit boards (PCB) with a full selection of high performance and low-cost materials from leading suppliers around the world. Aluminum PCB consists of a dielectric metal base with a bonded copper circuit layer to create superior heat transfer to help cool components while eliminating problems associated with managing fragile ceramics.
Rocket PCB works to be the best aluminum PCB manufacturer when it comes to exceeding all customer expectations. We provide a wide range of electrical and thermally conductive interface pads, thermally conductive gap fillers, thermal phase change materials and thermally conductive electrically insulating materials, as well as specialized equipment for high volume manufacturing.
Aluminum-backed PCBs can consistently increase durability and long-term reliability of a final product through temperature control and associated reductions in failure rates. Aluminum designs also deliver better mechanical stability and lower thermal expansion levels than other available materials.
Aluminum PCB Layers
Aluminum PCBs are a unique layered system comprised of the following layers.
Circuit Layer:
Printed circuit foil with thickness of 1oz to 5 oz.
Dielectric Layer:
The dielectric layer can have many different options which offer electrical isolation with minimum thermal resistance. Also used to bond the circuit layer and base material together. Each specific dielectric has its own UL recognition. See below for a listing of the different materials that we have in stock to ensure a wide variety of options with quick delivery.
Base Layer:
The base layer is most often aluminum but can also be copper. The most commonly used thickness is 0.040" (1.0mm) although many alternative thicknesses are available.

Key Requirements When Selecting an Aluminum PCB Manufacturer
For the most part, all PCB manufacturing follows the same production process regardless of where they are made. The only true differences in suppliers is the level of automation in their process, the newest technology and equipment, and having specific equipment designed to focus on certain types of end products.
For aluminum PCBs, there are several key items that a PCB manufacturer needs to consider if they are going to be able to effectively produce aluminum PCBs in any quantity, including:
Dedicated Imaging Equipment
Many of our aluminum backed PCBs go into LED applications that are much longer than the standard 18" x 24" or 20" x 24" production panels used in traditional PCB manufacturing. To be able to accurately register and economically produce these parts, a manufacturer must have either a custom piece of 60" wide UV light imaging equipment or a setup capable of screen printing (at one time) an image and then UV curing through an oven.
The old manufacturing process of screen printing half the image and then trying to hand register the first image while screen print the second half is much less effective.
Specialized Scoring Equipment
The more common equipment that can V score through traditional FR-4 materials is not suited to manage aluminum PCBs. To get the lowest cost possible, we need to get the best yield possible, which means we need to be able to place these parts as close as possible to each other on the production panel. Without V scoring, you must mechanically rout the parts out, which could result in up to 20% loss of your yield, subsequently increasing cost.
Our engineering team has many years of experience helping our customers design arrays that are the most cost effective for them to depanelize.
Greater Than 40-ton Punch Presses
For aluminum PCBs that are round or have unique features - you will want a manufacturer that can punch out these features. Trying to mechanically rout aluminum PCBs is a very costly way to get these features done in a production environment.
In-Line Hi-Pot Test
A unique requirement of aluminum PCB is that customers want to know that the product they are getting has passed a hi-pot test. While most PCB manufacturers can do this, it is usually a separate process in a lab that is not located in electrical testing. Rocket PCB's electrical test set up includes a hi-pot test, which dramatically reduces cost for the customer.
