LED aluminum PCB design

LED Aluminum PCB is composed of the circuit layer (copper foil layer), thermal insulation layer and the metal core layer. Circuit layer require great current-carrying capacity, thus should use thicker copper foil and generally the thickness is from 35um to 280um; Thermal insulation layer is the core technology of aluminum PCB, it is usually made up of special ceramics and fill special polymers, with small thermal resistance, good viscoelasticity, and has thermal aging ability, and can be able to withstand mechanical and thermal stress. Thermal insulation layer of IMS-H01、IMS-H02 and LED-0601 and other high-performance aluminum PCB are using this technology, [...]

Tips of high frequency PCB (RF PCB) design

In order to achieve more reasonable design and better anti-interference ability for high frequency PCB(Microwave RF PCB), design engineer should consider the tips as following: Use inner layer as power ground layer, which will have the effect of shielding and even decreasing spurious inductance, shorten length of signal wire, reducing Cross interference between signals. Circuit layout must be turn with 45 degree angle, which will help to reduce high frequency signal emission and coupling between each other. The shorter the better for length of circuit layout. The less the better for through holes. Layout between layers should be in vertical [...]

A Look Inside The PCB Design Process

Printed Circuit Board (PCB) Design, also referred to as PCB Layout, is the first step toward a successful PCB assembly. At this stage in the PCBA Manufacturing process, an engineer has decided the circuitry of the printed circuit board, and the layout can be designed.     Using PCB design software, the designer will design the component placement and routing of electrical connectivity on the printed circuit board. From RF/Microwave to High-Speed Designs, the Hitech Circuits design team can tackle any type of technology you require. Hitech Circuits designs with manufacturing in mind, meaning a smooth transition to production. Once [...]

Successful Flex Circuit Design Guidelines

With the use of sensors and technology in everything from mobile phones to refrigerators to automobiles to wearable medical devices, circuit boards are a component in many different types of products. In today’s world of electronics, any product with an on/off switch contains a circuit board. Due to their versatility, the use of flex circuits is one of the fastest growing product market segments.   With the introduction of flex and rigid-flex circuits, engineers have been given the opportunity to be more creative in designing new and innovative products. Flex and rigid-flex boards are built to fit into tight, three-dimensional [...]

FR4PCB vs. Aluminum PCB vs. Copper base PCB vs. Ceramic PCB for led headlight

For the PCB boards now in application to LED headlight, there are mainly four kind of materials, FR4 PCB, Aluminum PCB, Copper PCB and Ceramic PCB. It is a good deal to understand the distinctions for these four types PCB. Which PCB you choose depends on the circuit design construction of the headlight. FR4 PCB vs. Aluminum PCB Price Comparison In the cost comparison, the Aluminum PCB is more expensive than FR4, as well as more superior in performance. Thermally conductivity Aluminum PCB has a great capability of thermal conductivity than FR4 which makes them play an important role in [...]

How to Clean PCBs in Our Daily Manufacturing Process?

Printed circuit boards, especially those used in PDAs (personal digital assistants) like cell phones, get a lot of abuse. In addition to collecting dust and dirt that penetrates the cases of cell phones, e-book readers and similar hand-held devices PCBs have been known to suffer from immersion in and splashing from liquids in day to day use. As a result, a service industry has emerged to provide cleaning and repair services for PCBs subjected to contaminants but not physical breakage in PDAs and larger devices. Cleaning a Printed Circuit Board (PCB) to service a high-use product is as delicate a [...]


Flex circuit boards offer numerous advantages over rigid circuit boards. The ability to place circuits on a thin dielectric film means that flex circuit boards can fit in smaller spaces, allowing for electronics to be smaller and lighter and to contain more features. However, some product designers may wonder whether flex circuit boards are as reliable as rigid circuit boards. Does all that flexibility potentially lead to more issues or a shorter life down the road?   Flex Circuit Boards are Highly Durable You aren’t sacrificing reliability when you choose flex circuit boards over rigid circuit boards. Flexible circuits are [...]

What Components Should Be Tested On A PCB and PCB assembly?

All electronic products need to be tested even if they are accurately designed and professionally fabricated, as they can be prone to malfunctions and problems. Printed circuit boards are composed of various electrical components which need to function correctly, and PCB testing is essential to test that each component is functioning. Capacitors Testing a capacitor in a printed circuit board requires one end of the capacitor to be removed from the circuit board. Then, it’s essential to make sure that the power supply of DC voltage matches the range of the capacitor to prevent overloading of the device. When you [...]

Do you know what is a PCB or Printed Circuit Board?

PCB or Printed Circuit Board is the traditional name for the bare board of which we produce with the layout data and which will be used to mount the components on. A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate.Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it. When the board has only copper tracks and features, and no circuit elements such as capacitors, resistors or active devices have [...]
