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 [...]

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 [...]

RF PCB Layout: Interconnect Losses

Your trace geometry and layer stack will have a major effect on signal integrity as you route high frequency analog signals throughout your board. Newer designers will likely default to a microstrip geometry, possibly with guard vias to provide isolation between different circuit blocks and to suppress radiated emissions. The question of which trace geometry to use is about more than isolation; it is also about avoiding losses due to dielectric absorption, roughness losses, and scattering from your PCB substrate. The alternative to using microstrip transmission lines is to use stripline transmission lines. Routing striplines on a dedicated interior layer [...]

Mpcb or metal pcb

Thermal substrates for high watt density SMT applications Metal core thermal PCB (MCPCBs, MCB, IMPCB or IMS) are widely used in applications where a dense wattage calls for a good thermal heat dissipation. The thermal efficiency gained by a metal based board allows for downsizing designs and removal of hardware. To avoid short circuits, there is an electrical insulation between the copper traces/pads and the base metal using a tailored dielectric layers with high thermal conductivity. Thanks to metal core PCB, power densities can be increased while components remain cool, increasing life and durability. It also allows modules [...]

Electronics Manufacturing Steps of PCBA Circuit Board

Let’s understand the electronics manufacturing process of PCBA in details: Solder Paste Stenciling First and foremost, the PCBA company applies a solder paste to the printed circuit board. In this process, you need to put solder paste on certain portions of the board. That portion holds different components. The solder paste is a composition of different tiny metal balls. And, the most-used substance in the solder paste is tin i.e. 96.5%. Other substances of solder paste are silver and copper with 3% and 0.5% quantity respectively. The manufacturer mixes paste with a flux. Because flux is a chemical that helps [...]
