(M1) Explain the benefits of usingautomated techniques for the manufacture of an electronic circuitTheadvantages of the use of lighting techniques to produce electronic circuits isthat some of the machines in the SMT program used under appropriate to create avideo image on the plan design. This allows PCB to minimize the risk ofredevelopment of this project by combining design errors such as unimportantsymbols, signs of defects, etc. before the start of the conference process.Hand-assembling a PCB can be extremelydifficult; not only are electronic components and boards getting smaller, butevery part must be perfectly soldered. With shorter development cycles,engineers usually do not have time to “learn from their mistakes.
” Themachine-assembled machine is closely related to any part of the production,which may eliminate the changes that may arise from the function. Thiscoordination facilitates the creation of additional PCB documentation if everrequested. You do not need professional and electronicengineers if you want to invest in. There are no verbal and unmanaged searchoperations. SMT machines combine the creation of a quality and affordablearchitecture that can quickly and efficiently work, warehouse search and searchbrush reduce the likelihood of future problems.The investment allowance varies from day today, depending on the complexity of the Commission.
Facilitate formattingcoordination service not only to give you resolution of mind so you know thatyour board will be returned in serious condition but schedule your schedule inother design and production areas. Many steps can be taken when compared toproduction time and money.Task 2Singlesided PCB is the basic simple PCB, parts is layout on one side and the circuitis on the other side. As there is only layer conductor, it is called singlesided PCB.
It is restricted in the circuit design, so it is more frequentlyused in the early printed circuits PCB.Singlesided PCB diagram mainly use network printing. That is to print resist on thebare copper, etch and then print solder mask, finally punching to finish partsplated hole and profile. MultilayerPCB is as the name implies, that is PCB boards with more than two layers, forexample, four layers, six layers, eight layers, etc. Since it is double-sidedmultiple, then they have many common features with double layers PCB: more thantwo layers conductive traces, separated by insulating material between thelayers, and the layer between the conductive traces must connected throughdrilling, lamination as required.
Theadvantage of multilayer circuit boards is with multi-layer conductive wire,high density drilling, the volume will be relatively small, and the weight isrelatively light accordingly. The high-density line reduces the space ofcomponents which means more reliable. As there are more layer’s circuits, itwill be flexible for PCB design / layout. And it plays the role of impedancespeed transmission circuit forming.Circuitboards for printed circuits are the result of the development of electronictechnology to high speed, a lot of work, performance, and low. With thecontinuous improvement of technology electronic, especially in applicationswider circulation wide range of integrated and complex, many needs on PCB witha number of provisions of the line penalty, with blind and buried, high-tech -high density, upgrading, high layer to meet market demand.
Task 4 Back Annotation is the process of putting delaysfrom a given source for the. cells in a netlist during netlist simulation.Back annotation willopen an additional window with a set of options. This will put parasiticresistors and capacitors in the new extracted view. The back-annotation functions are used to extract timing delays fromyour post layout data.
Backannotation provides a facility to make changes in the PCB design to the netnames and component reference names, either manually or in the case ofcomponent names automatically, and to then apply those changes back to themaster or original Schematic design. Forward annotation isthe process of sending schematic changes to a corresponding PCB layout. NIMultisim automates the process of forward annotation.Forward annotation isa critical step in the design cycle and is the main process to amend PCBlayouts with fixes to errors that were discovered through prototype testing. Asimple and easy-to-use procedure ensures that all updates to a schematicare automatically realized in PCB layouts. Design rule checking (DRC) is the area ofelectronic design automationthat determines whether the physical layout of a chip layout satisfies a seriesof recommended parameters called designrules.
Design rules are a series ofparameters provided by semiconductormanufacturers that enablethe designer to verify the correctness of a mask set. Design rules are specific to asemiconductor manufacturing process. A design rule set specifies certain geometricand connectivity restrictions to ensure sufficient margins to account forvariability in semiconductor manufacturing processes, to ensure that most ofthe parts work correctly.
