Dhizaini marobhoti ane vanachandagwinyira pcb bhodhi pasina kufunga kwekudzivirira iyo pcb kubva kukundikana kwekutetemera kunokonzerwa nema mechanical resonance. Kukundikana uku kunogona kukonzeresa kumatambudziko akakura senge akaputswa insulators uye maaccitors, kudonhedza zvinhu, pcb wiring discontinuities, solder nzvimbo kutsemuka, pcb board layering, magetsi mapfupi maseketi uye kudamburwa kweplating barrel pad. Kuti ubvise uku kukundikana, anoshanduka akaomarara akadhindwa wedunhu mabhodhi anodikanwa.

What is rigid flexible PCB?

A printed circuit board in which rigid and flexible circuit plates are laminated together to weld parts on rigid parts and bend parts instead of wired connections. Chikamu chakaomarara chinogona kunge chakaita seyakaomarara pcbp, panogona kugadzirwa zvinhu zvacho pamativi ese ebhodhi uye zvidimbu zvehukama zvinogona kugadzirwa, nepo chikamu chinoshanduka chinogona kusunganidzwa mumatanho mazhinji, asi izvo zvikamu zvinogona kusunganidzwa iyo nekuti iyo inochinjika chikamu chinoshandiswa kubatanidza chete pakati peyakaomarara matunhu edunhu.

Kubvisa zvinongedzo kubva dhizaini kunozivisa zvinotevera zvivakwa kudunhu. Kufambisa kwemasaini kubva kune chimwe chikamu kuenda kune chimwe pasina kurasikirwa kana jitter (ruzha) Bvisa matambudziko ekubatanidza senge anotonhora macontact.Free up space and reduce weight. Makes the circuit vibration-proof and can be installed in applications with moving parts.

Dhizaini inoomarara inoshanduka pcb:

A variety of software is available for designing rigid flexible PCBS, but Altium provides the best 3D visualization of rigid flexible PCBS and is highly recommended. Paunenge uchigadzira zvikamu zvakaomarara uye zvinopfava, zvakakosha kuti usarudze hupamhi hwemhangura zvinoenderana nechishandiso.

This indicates that the same amount of current must be used in the rigid and curved parts with different trace widths due to the thickness, area and permittivity of the material. Rayming PCB nevanjiniya veMagungano vanogara varipo kuti vabvunze pane chaiyo wiring upamhi uye inonakidza zvinhu zveyako yekushandisa frequency uye kunyorera.

Kufananidza kweFlexible PCB:

Pepa dhora prototype yakakosha mukugadzira maseketi anoshanduka. This simple practice can help designers prevent many errors by showing problems related to bending early, and can save time and money. Izvi zvinobatsira mugadziri kufungidzira iyo yakakombama nharaunda uye sarudza kurudyi nzira yekutsvaga mhangura kudzivirira kubvarura kana kuregedza.

Dhizaina mhangura yekuteedzera nekusarura:

Keeping extra copper in the design increases the dimensional stability of the flexible circuit. Kune imwechete-rukoko uye maviri-mativi akasanduka anochinja dhizaini, kurerekedza kwakatenderedza trace mhangura tsika yakanaka. The addition or removal of additional copper depends only on the application, but if the designer has additional copper with bias, traces with bias should preferably be used for mechanical stability. Uye zvakare, kuita kudaro kunogona kudzikisa huwandu hwendarira hwakagadziriswa, inova nharaunda inoshamwaridzika maererano nekushandisa kwemakemikari.

Inosunga chimiro mune akawanda-masenduru kuchinjika:

Staggered length design is usually used to facilitate the design of multi-layer flexible circuits. Mune ino hunyanzvi, dhizaini inowedzera zvishoma kureba kweimwe neimwe inotevera inoteedzana dura, inova ka1.5 zvakapetwa nehuremu hwenzvimbo yega. Izvi zvinodzivirira pakati kukombama kweiyo yakakomberedzwa dura mune yakawanda-rara inoshanduka dunhu ine yakasarudzika dura. By this simple method, the tensor strain and i-beam effect established on the outer metal layer can be eliminated, which may be a key problem in dynamic applications.

Track corner wiring:

Some of the problems associated with wire routing in flexible circuits include keeping the number of crossings to a minimum so that layers can be reduced to save money, and the second is the bending Angle of traces in flexible circuit design. Zvisaririra zvinofanirwa kukombama uye kupetwa makona, sezvo makona akapinza anogona kuteya mhinduro panguva yekucheka uye anogona overetch uye zvichanetsa kuchenesa mushure mekurapwa. Kana paine marara emhangura kune ese mativi edenderedzwa, mugadziri anofanirwa kugadzira nzvimbo inokwana 2-2.5 zvakapetwa nehupamhi hwemutsara kudzivirira chero magetsi emagetsi madiki uye kukosheswa kwakakodzera. Kufunga iyi mirairo kunogona kusimudzira kupararira kwemasaini uye kudzikisira kuratidzika panguva yekutendeuka.

Yakaomarara kukotama shanduko chikamu:

Iwo mashoma madaro kubva kune akaomarara kusvika kune anoshanduka echinzvimbo enzvimbo kusvika kumucheto wegomba rekubvisa uye akafukidzwa kuburikidza negomba haafanire kunge ari pasi pe0.0748 inches. Paunenge uchigadzira chinhambwe pakati peasina kufukidzwa kuburikidza neburi uye mukati nekunze kumacheto kwecheka, zvekupedzisira zvakasara zvinhu hazvifanire kunge zviri pasi pe0.0197 inches.

Vanachandagwinyira – kusanduka inowanikwa unhani kuburikidza buri:

Iyo yakakurudzirwa chinhambwe chinhambwe pakati peyakaomarara muchinjikwa chikamu uye yakafukidzwa kuburikidza nemakomba eiyo solid solid switch interface yakakura kupfuura 0.125 mukati. Violation of this rule may affect the reliability of the plating through hole.
