Additional requirements for the efficient design of high-speed buses may be dictated by the needs of a specific application. For example, a 266 MHz, 64-bit DDR RAM interface will be sensitive to skew between the different byte lanes. Large parallel buses also have the potential to generate simultaneous switching output (SSO) noise and voltage droop. All of these factors translate into the need to manage the transient current demands of a particular application through proper design of the

Since the PCB design enter into a high-speed era, It was suggested there will be only the front-end and back-end in hardware design (front-end refers to the IC design, back-end refers to the PCB design) in ten years. As long as a system engineer integrate them and it will be ok. It is doubtful for someone that if it is neccessary to learn the basic knowledge of the hardware. In fact, in spite of IC or PCB engineers, they much have the knowledge such as R, L, C as well as the basic circuits.

There are currently 2430 PCB manufacturers worldwide, according to industry data presented by Mr. Walt Custer from the Custer Consulting Group at this year’s Apex Show, which evertiq attended.

Produce your own single-sided flexible pcb using a solid ink printer, copper-coated polyimide film, and common circuit board etching chemicals. You will find flex PCBs inside most cellphones or similar miniaturized gadgets. Flex PCBs are useful for making tiny cables and extremely lightweight circuits. However, few shops yet make custom flex PCBs for reasonable prices in small volumes.

Double Sided PCB

Double Sided PCB are a step above single sided in their complexity. Double Sided PCB require plated through holes to provide better anchoring for soldered components and front to back electrical continuity. Most designs require soldermask front and back along with a silkscreen layer for component designators. Very often double sided designs utilize a mixed technologies of through hole (PTH) and surface mount (SMT).

FC4500-50PRO plate cutting machine

The advantage of its high accuracy, low cost, cutting edge with good effects, has been fully applied to FPC, membrane switch, backlight industry, both in the semi-pad window in the PI covering membrane, carrying precise appearance of flexible circuits, and the thermosetting adhesive film, can be a high-speed, high-quality completion. The machine is so compact that making equipment more compact and elegant, small footprint, and easy to choose the installing space. It is the best tool for replacing Rule Die proofing and laser-cutting, it is cut by knife, and normally it has the following advantages compared to sampling methods:

Multilayer PCB

Multilayer PCB consist of 3 or more circuit layers bonded together by a thickness of insulating material called prepreg. Prepreg is B stage epoxy impregnated fiberglass. Multilayers are generally considered to be the most sophisticated PCB product due to their construction methods and design complexities.

Single sided PCB represent the least sophisticated (and thereby least costly) of the PCB products. These boards usually do not require plated through holes and only have a circuit pattern on 1 side. Quite often single-sided boards are referred to 'punch and crunch' due to the fact that high volume runners are profiled with tool and die.

The common FPC packing is to stack the flexible circuits of 10 ~ 20pcs together, and fix in a cardboard with paper rolls to avoid using tapes, because tape adhesives which contain chemical substances, if be exudative it will easily lead to discolor the terminal oxidation. When the basement membrane is a polyimide film as it can easily absorb moisture, flexible printed circuit boards should be loaded together with silica gel and desiccant into the polyethylene bags and pressurize the bags. And then cased into corrugated boxes with cushioning materials. Due to the unique shape of the FPC, different form should be used different packings.
