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 [...]

ARE FLEX CIRCUIT BOARDS AS RELIABLE AS RIGID CIRCUIT BOARDS?

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 [...]

Inspection Method of PCB assembly Short Circuit

PCBA(Printed Circuit board Assembly) short circuit is a relatively common failure in PCB Assembly. once PCB assembly occured short circuit, which requires the professional electronic engineers to analyze the reason and deal with it to avoid irreparable losses.   Inspection Method of PCBA Short Circuit   If the board (PCB) will adopt manual soldering, developing a good habit is much vital. First, check the circuit board visually before soldering, and use a multimeter to check whether the key circuits (especially the power supply and ground) are short-circuited or not; Secondly, once soldered a chip to the board, using a multimeter to check whether the power supply and ground are short-circuited or not; In addition, do not throw the solder iron randomly when soldering. If you throw the solder onto the [...]
