Our team of engineers and CAD/CAM operators are available to discuss any project needs that our customer may have as we are fully licensed and utilize industry leading tools, including Cadence Allegro, Mentor Expedition, Mentor's PADS, Altium, Valor for DFM Analysis. Our Capabilities Encompass The Full Design Flow From Start To Finish Including: Micro BGA / Micro Via / Blind and Buried Vi

Talk Something about Impedance PCB

 Considerable signal reflection and falsification will occur, thus resulting in design failures if there is no impedance control in the PCB. Normal signals, such as PCI bus, pci-e bus, USB, Ethernet, DDR memory, LVDS signal, etc. also require impedance control. Finally, PCB design will be achieved by impedance control and it can put forward for PCB technology. After talking with PCB manufacturers and combining with the use of EDA software, the trace with impedance control can be made according to the integrity of signal. Different routing methods can be calculated to obtain the corresponding impedance. Microstrip line It is composed of a ribbon conductor and ground plane, with dielectric in the middle. If the dielectric constant of the dielectric, the width of the line, and the distance to the ground plane are controllable, the characteristic impedance of the dielectric is also controllable, and the accuracy is less than + / -5%. Stripline A strip is a strip of copper between two co

To find the cheapest pcb manufacturer china

 Breadboards are great for prototyping circuits, but they aren’t so good for actually using the thing you’re building. At some point, you’ll probably want to make a project more permanent. The best way to do that is to put it on a PCB. In this tutorial, I’ll walk you through the process of designing a PCB layout and getting it printed by a custom PCB manufacturer. The performance of your circuit will depend greatly on how it’s laid out on the PCB, so I’ll give you lots of tips on how to optimize your design. You can always etch PCBs at home with a process that’s similar to developing prints from photographic film. But that method is messy and it uses a lot of chemicals. It’s much easier (and cheaper) to get your PCB made by a professional manufacturer. To demonstrate the process, I’ll use an online service called EasyEDA to design a PCB layout for an LM386 audio amplifier, then I’ll have it manufactured and show you the results. Their free online design software is easy to use and the

Printed Circuit Board (PCB) Materials

 Printed circuit boards (PCBs) are usually a flat laminated composite made from non-conductive substrate materials with layers of copper circuitry buried internally or on the external surfaces. They can be as simple as one or two layers of copper, or in high density applications they can have fifty layers or more. The flat composite surface is ideal for supporting the components that are soldered and attached to the PCB, while the copper conductors connect the components to one another electronically. The six basic components of a standard printed circuit board are: Prepreg Laminate Copper foil Soldermask Nomenclature Final finish Prepreg is a thin glass fabric that is coated with resin and dried, in special machines called prepreg treaters. The glass is the mechanical substrate that holds the resin in place. The resin – usually FR4 epoxy, polyimide, Teflon, and others – starts as a liquid that is coated onto the fabric. As the prepreg moves through the treater, it enters an oven secti

What is a Printed Circuit Boards (PCB)?

 Printed circuit boards (PCBs) are the foundational building block of most modern electronic devices.  Whether simple single layered boards used in your garage door opener, to the six layer board in your smart watch, to a 60 layer, very high density and high-speed circuit boards used in super computers and servers, printed circuit boards are the foundation on which all of the other electronic components are assembled onto. Semiconductors, connectors, resistors, diodes, capacitors and radio devices are mounted to, and “talk” to one another through the PCB. PCB’s have mechanical and electrical attributes that make them ideal for these applications.  Most PCB’s manufactured in the World are rigid, roughly 90% of the PCB’s manufactured today are rigid boards. Some PCB’s are flexible, allowing the circuits to be bent and folded into shape, or sometimes they are used where the flexible circuit will survive hundreds of thousands of flex cycles, without any break in the circuits.  These flexib
