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 [...]

PCBA assembly Appearance Inspection Instructions

Printed circuit board assembly (PCB assembly, PCBA), often use abbreviations—— PCBA, is an important electronic parts, is the support of electronic components,the provider of the electronic circuit connection.Because it is produced by using electronic printing technology, it is called "printed" circuit board.Before appears in the printed circuit board, electronic components of interconnection between relied on wires connected directly and form a complete circuit. Now, the circuit bread board only to exist as an effective experiment tool,but the printed circuit board in the electronics industry has become the dominant position. But most people still don't know what is PCBA  appearance inspection [...]

Why Flex and Rigid-Flex PCB Tooling Costs Higher

There are many factors that influence flex and rigid-flex PCB, here are some of them. Tooling charges comes down to volume. For rigid-flex and/or flex prototypes and small volume runs, most are manufactured with laser cutting or some type of mechanical routing. This is used to create the surface mount features in the Coverlays, part outline, and if required, the outline of the stiffeners. Electrical testing on these lower volumes is typically done with a flying probe. In volume production of flex and rigid-flex circuits, you need to switch over to steel rule dies or male/female punch and die sets. These steel [...]

Printed Circuit Board Assembly

Printed Circuit Board Assembly The circuit board before the assembly of electric components is called Printed Circuit Board. After the soldering of all the elements on the board, it is known as Printed circuit Board Assembled, we called PCB assembly. The complete process of component's assembly is called Printed Circuit Assembly or Printed Circuit Board assembly or PCB board assembly. In this process, different automatic and manual assembly tools are used. We are assembler that offer PCB assembly. PCB boards cannot perform any function until and unless its assembly is completed. PCB assembly is a process of assembling and soldering [...]

The Basic Knowledge of PCB in PCB Assembly

In today's society,PCB is used widely in our all-sides life.As a necessary part, it plays an important role. Therefore, we have to have a good knowledge of PCB. Today I summarized PCB knowledge for you.  Definitions: For standard PCB, it is the combination of bare board and components on it. While for bare board PCB, it is called printed wiring board. We usually call it PWB. (1) Traces: The base material of PCB is comprised of dielectric, heat insulation, uneasy to bend materials. On its surface, we can see thin traces, its material is copper. Originally the copper covered the [...]
