JHYPCB is a professional PCB board manufacturer, offering prototype PCB fabrication, small batch circuit board and PCBA manufacturing services.
Generally, a PCB made of a flexible insulating substrate is called a flexible PCB or FPC, and a circuit board that combines a rigid PCB and a flexible PCB is called a rigid-flex PCB. It meets the needs of today’s electronic products in the direction of high density and high
With the rapid development of electronic products, components have become smaller and smaller, and the requirements for PCB stencil have become higher and higher. According to different production processes, stencil mainly includes chemical etching, laser cutting, and electroforming. The SMT stencil is mainly composed of a screen frame, wire mesh,
PCB, or Printed Circuit Board, is a substrate produced by circuit printing technology, which is used to carry various electronic components, so as to combine to achieve circuit functions. After core processes such as circuit film exposure, development, etching, and electroplating on the PCB copper clad board, all the copper
Introduction Low cost and high output have always been the eternal pursuit of all companies. Through the Design For Manufacturability(DFM) of the printed circuit board, the design department and the production department can be effectively connected organically, and the design, development, and production can be coordinated to unify the standards,
Design For Manufacturing (DFM) studies the relationship between the physical (mechanical and electrical) model of the product itself and the manufacturing and processing system. It incorporates it in product design to integrate it with the requirements of the entire manufacturing system. It makes the designed product easy to manufacture, reduces
Depending on the design of the circuit board, the price will vary depending on the material of the circuit board, the number of layers of the circuit board, the size of the circuit board, the quantity, the production process, the smallest line width and line spacing, the smallest aperture and
Have you ever made a list of grocery items before going to a store? Your answer would probably be yes. It’s widespread, and almost everyone makes a list. The list can be on paper or on your mobile. We often create lists to keep everything in mind. We make the
What is SMT solder paste stencil? SMT stencils are the medium you use to transfer that solder paste onto the PCB. Stencils consist of a foil made of stainless steel that is laser cut to match the places where surface mount devices will go on the board. This process creates
The printed circuit boards (PCB) have been an integral part of several electronic circuits for a long time now. So, most electrical engineers involved in the production of these circuit boards are familiar with different materials used to build them. FR4 is one of the most popular materials used to
With the increasing requirements for “light, thin, short, and small” printed circuit boards, the demand of downstream industries has gradually shifted to higher-end products. FPC boards, HDI PCBs, and high-end Multilayer PCB board technology have become the main direction in the future. The downstream applications of the PCB industry are
Metal Core PCBs are widely used, primarily because of their higher thermal conductivity. They can dissipate heat during operation, even if there are high-power dissipating components. FR4 and other non-metallic substrates cannot work for a long time in the case of high heat production or high temperatures. They have a
Things Needed for Printed Circuit Board Assembly Following electronics parts and consumables are needed for PCB assembly. Printed Circuit Board Electronic components Soldering materials including solder wire, solder paste, solder bar, solder preforms (depending on the type of soldering to be done) Soldering flux Soldering equipment including a soldering station,
These ten tips will help new PCB designers improve their PCB board design. This will make their circuit boards easier to produce and increase the yield. This entry will discuss how to apply manufacturing design concepts, and assembly design concepts to PCB design, and how to use these concepts in
Differences Between Single-sided PCB and Double-sided PCB Single and double-sided printed circuit boards share the same material make-up: FR-4, which is a form of fiberglass mixed with epoxy. In modern manufacturing, this is usually layered with copper for conductivity and then coated in solder mask for a professional finish. Sometimes,
FPC(Flexible Printed Circuit Board) impedance control circuit is also known as impedance strip. When the current required to pass through the circuit is greater than the maximum that the circuit can bear, it is necessary to use impedance to control the excess flow, which is the principle of impedance control.
At present, the demand for high-TG PCB circuit boards in various industries is getting higher and higher, which requires PCB substrate materials with higher heat resistance. The emergence and development of high-density mounting technologies represented by SMT and CMT have made PCBs In terms of small aperture, fine wiring, and
The birth and development of FPC and PCB have created this new product- Rigid-flex PCB board, Therefore, it is a printed circuit board, which combines an FPC( flexible printed circuit) with a rigid circuit board by pressing or laminating processes, and according to the relevant technical requirements to form a
