Printed Circuit Board can be classified into different types according to different standard, such as single layer PCB, double layer PCB, and Multilayer PCB . But now we are going to introduce you the Aluminum-Backed PCBs. Aluminum-backed PCBs are designed in much the same way as their copper-backed counterparts by using the aluminum or copper substrate board. These types of boards have a thermal clad layer which disperses heat quite efficiently. At the same time, the layer is also cooling components which results in an increase in the overall performance of your PCB. Please check the above photo to know about the structure of the aluminum PCB. Let’s look at aluminum printed circuit boards a bit closer and figure out why we choose them. Here are some advantages of Aluminum-backed PCBs when come compared with fiberglass PCB boards. 1. Heat dissipation. This is the most obvious advantage. Aluminum is one of the best materials available for dissipating heat away...

As we all know, quality is the life of products. So for a PCB manufacturer ，how to guarantee the quality of the PCBs is the key question we have to solve first. For Fast Turn , we focus on the two main factors for the PCB quality control. Quality Control in PCB Design PCB design is the first step for a PCB board. Once if there is any problem in the design, we will have trouble going on with the project. For Fast Turn. Even though some of the designs from our clients are not from our own layout team, It is our responsibility to have a rigorous check about the PCB design. We will go from the following aspects: • Validity of PCB design file has to be ensured. Our engineer team will review the file for free to make sure the design file is valid and the corresponding procedures are implemented. If not, our engineer team will give feedback and our suggestions to revise the design. • Manufacturability of PCBs has to be ensured. If the file is good, our engineers w...

Recent years, modern automotive industry has improved itself to be focus more on handling, sensing, information transmission and recording from the traditional automotive industry which strives more for mechanics, power, hydraumatic and transmission. To achieve the automotive modernization and digitalization, HDI PCBs have become the first option. So for the automotive HDI PCB manufacturers, how can they be capable? As we all know, automotive HDI boards require high reliability and security. So the automotive HDI PCB manufacturers needs to meet the following requirements: 1.HDI PCB manufacturers have to be capable to fabricate the boards in terms of technologies of high HDI fabrication capability and quality control system. As we also know, to be an automotive manufacturer, one supplier has to be authorized by a third party for some certification like ISO9001 and ISO/TS16949. This is the qualification to an Automotive PCB supplier， which also means that the...

Combining the supporting function contributed by rigid boards and the functions of high density and flexibility contributed by flex boards, rigid-flex boards enjoy the irreplaceable advantages of lightness, thinness and small size of electronic products. To meet these advantages, the designers mainly adopt the blind/buried via and High Density Interconnecting (HDI) techniques. This blog is going to state some blind/buried via technique in HDI rigid-flex PCBs . Above all, we have to take a closer look for the dedicated material for the HDI rigid-flex PCBs. We usually use the FR4 copper foil for the rigid parts and the specific PI for the flexible part. Because of the easy occurrence of delamination of rigid-flex boards, acrylic acid adhesive should be picked up as pre-preg of rigid-flex associative part , in order to meet the viscidity requirement. Silicone rubber as lamination material and PET release film as mold cleaner are used during the lamination processes. All...

Rigid-flex boards consist of multiple layers of flexible PCBs attached to a number of r i gid PCB layers . As it’s name shows, it has the advantages of coming the function of the rigid boards and flex boards. To be accurate, rigid-flex PCBs have better advantages over just the rigid or flex boards. For one, rigid-flex boards have  lower parts count than traditional rigid or flexible boards because the wiring options for both can be combined into a single board. The combination of rigid and flexible boards into a single rigid-flex board also allow for a more streamlined design, reducing the overall board size and package weight. Besides, using flex-rigid PCBs rather than traditional PCBs and discrete connection can reduce the assembly time of the final product and ultimately lead to a more reliable product. The growth of the use of rigid-flex solutions in recent years is a testament to the utility provided by rigid-flex solutions. The rigid-flex PCBs...

HDI printed circuit boards are circuits that offer much higher wiring densities per area than standard circuit boards, with finer lines and spaces, smaller vias and higher connection pad density. Fast Turn PCB has improved and upgraded our manufacturing facilities in 2011 to include HDI board fabrication and now provide manufacturing HDI PCB service in our comprehensive list of PCB fabrication capabilities. Using HDI instead of conventional PCBs can reduce the thickness size and weight as well as to enhance electrical performance of the PCB. This is due to the micro-via and buried via in the HDI PCB sequentially laminated using various insulation materials and conductor wiring for higher density of routing. There are much to learn about the HDI PCB fabrication. Firstly, let us start with the following pic to learn about the HDI technology in holes： 图一：HDI TECHBOLOGY IN HOLES And then, we can get a touch about the HDI process as the following pictures show: ...
