Free PCB Software
Haloe posted a topic in Electronics chit chatI plan to design a serious of panels for my next project. I was going to order ALLPCB.COM as they seem to obtain many good reviews. I want to know what free PCB software would be easier to use? Both Windows and Linux are available for me.
How do you get a PCB when you need in your project?
Haloe posted a topic in Projects Q/ANow, I am considering about to do a new project, and this project will according to a WIFI transmitter. So now, I am considering about is it better to buy a circuit board then a DIY? After all,it is too hard for a school student to afford it if they are expensive. What are you use if you need some boards? Diy one or buy one. Feel free to leave a comment, cause I don't know how much it will cost if I bought some PCBs.

How to Design a PCB Layout
Haloe replied to Lasseryie's topic in Sell/Buy electronics - Job offer/requestsstep1 You’ll first take the schematic that you finished earlier and turn it into a new PCB layout. step2 You’ll then place and rotate all of your components, working to minimize the length and crossing of airwires (more on this later). step3 You’ll finish up your placement process by resizing the dimensions of your board layout in preparation for routing.
The advantages of Flex PCB
Haloe posted a topic in Sell/Buy electronics - Job offer/requestsRecently i learned some knowledge of flexible PCB. I want to share some advantages. Flex PCB(also variously referred to around the globe as flex circuits, flexible printed circuit boards, flex print, flexi-circuits) are members of electronic and interconnection family. They consist of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits. It is now one of the most important interconnection technologies in use for the manufacture of many of today's most advanced electronic products. Generally speaking, there are 5 advantages in using Flex PCB than traditional rigid PCB. 1. Size Today's market for electronic interconnect, demands an increased number of I/Os with a high degree of performance and reliability in increasingly miniaturized packages. Constant consideration to further reduce package size is required to support tomorrow’s sophisticated product requirements. Being inherently thin, lightweight, and flexible, flex interconnect facilitates miniaturization, making it a prime candidate for portable devices and applications where space is at a minimum. Flexible PCBs have innate mechanical and electrical properties that make them an ideal selection for emerging applications. 2. Reliability Flex circuits are a reliable alternative to conventional wiring. The thin flat conductors and insulation that make up flex circuits provide more surface area than traditional wiring resulting in better heat dissipation and current carrying capacity. Flex circuits offer repeatable reliability and facilitate the replacement of heavy bulky wiring harnesses. 3. Malleable Flex circuit technology allows for three-dimensional configurations. Flex circuits have the ability to be formed around obstructions through thin openings and into confined areas. Utilizing Flex circuits for three-dimensional applications increases the reliability and integrity of the electrical connection when connecting to peripheral devices. This is achieved by removing unnecessary plated through-holes or surface-mount pads, which are created to house mechanical connectors. 4. Performance Uniform dielectric and conductor thicknesses, favorable dielectric constant and increasingly finer line and spacing geometry provide improved impedance control required for dense, high-speed signal routing. 5. Cost If the above factors don't give you reason enough to move to flex circuits, you should also consider the costs involved. Generally speaking, you really do get more for your money with flexible circuit technology. It is not uncommon to replace several electronics components with a single flexible circuit that provides equal to or better performance for your system.
Self-introductionHi, everyone! I’m a student. I really like electronic products. It’s a honor to meet everyone in this forum. I want to learn more about electronic knowledge and make more friends here. I hope we can communicate each other in the future. Looking forward to our common progress!
