Mune ino blog positi, isu tichanyatso tarisisa maitiro ehumidity uye hunyoro pamabhodhi akaomesesa-flex edunhu tokurukura kuti vagadziri nemainjiniya vanogona kuderedza sei izvi.
Mumunda wemagetsi, rigid-flex circuit boards ari kuramba achizivikanwa nekuda kwemagadzirirwo awo akasiyana uye kushandiswa kwakasiyana-siyana.Aya mapuranga ematunhu anoumbwa neakaomarara uye anochinjika akaturikidzana anoabvumira kukotama, kupeta, kana kumonyoroka kuti akwane compact uye yakaoma midziyo yemagetsi.Nekudaro, senge chero chimwe chikamu chemagetsi, rigid-flex redunhu mabhodhi haadzivirirwe kune zvakatipoteredza zvinhu zvakaita sehunyoro uye unyoro.Muchokwadi, zvinhu izvi zvinogona kukanganisa zvakanyanya kuita uye hupenyu hurefu hwemabhodhi aya.
Zvose humidity (zvichireva kuvapo kwemhute yemvura mumhepo) uye hunyoro (zvichireva huwandu hwemvura huripo munharaunda) zvinogona kukanganisa rigid-flex circuit board.Kana yakafumurwa kune hunyoro hwepamusoro, hunyoro hunogona kupinda muzvikamu zvebhodhi redunhu, zvichikonzera kukora kwemarara esimbi uye zvikamu.Izvi zvinogona kukonzera conductivity kurasikirwa uye kuvimbika nyaya.Uye zvakare, hunyoro hunogona kukanganisa dielectric zvivakwa zve insulating zvinhu zvinoshandiswa mumabhodhi edunhu, zvichikonzera kuwedzera capacitance kana kuvuza ikozvino.Izvi zvinogona kutungamira mukukanganiswa kwechiratidzo, kushomeka kwekudzivirira, uye kukanganisa kwese kwebhodhi.
Rimwe rematambudziko makuru ane rigid-flex circuit mabhodhi kuvapo kwenzvimbo dzine mabhendi akasiyana-siyana, izvo zvinogona kugadzira kushaya simba.Kana yaiswa kune hunyoro, idzi dzisina simba dzinova nyore kukuvara.Hunyoro hunogona kupinda mumatanho anochinjika, zvichiita kuti dzizvimbe kana kudzikisira, zvichikonzera kuwedzera kushushikana pamatanho akaomarara uye zvichikonzera kuti bhodhi ikunde.Mukuwedzera, kunwisa unyoro kunogona kushandura zviyero zvechigadziro chinoshanduka, zvichikonzera kusaruramisa nehupamhi hwakaoma uye kudzivisa kushanda kwese kwebhodhi.
Kudzikamisa mhedzisiro yekunyorova uye kunyorova pamabhodhi akaomesesa edunhu, vagadziri uye mainjiniya vanoshandisa nzira dzakasiyana.Imwe nzira yakajairika ndeye kushandisa conformal coatings, iyo inopa chinodzivirira kubva kune zvakatipoteredza zvinhu, zvinosanganisira mhute yemvura uye kunyorova kwemvura.Aya mabhanhire anowanzo shandiswa kune akafumurwa simbi marara kudzivirira ngura uye kuwedzera kuvimbika kwese kwedare redunhu.Nekudaro, kusarudza iyo chaiyo yekupfekedza zvinhu uye kuona kufukidzwa kwakakodzera kwakakosha, sezvo kusakwana kupfeka kunogona kukonzera kuratidzwa kwenzvimbo kune hunyoro uye kuchengetedzwa kushoma.
Chimwe chinhu chakakosha ndechekusarudza zvinhu zvakanaka zveiyo rigid-flex circuit board.Zvishandiso zvinodzivirira hunyoro, senge polyimide, zvinowanzofarirwa kune zvidimbu zvinochinjika nekuda kwekudzikira kwadzo hunyoro uye kugadzikana kwedimensional.In kuwedzera, chivharo chekunyorova chinogonawo kuiswa mukugadzirwa kwebhodhi redunhu kudzivirira hunyoro kubva pakupinda mukati uye kukonzera kukanganisa.Izvi zvipingamupinyi zvinowanzogadzirwa nezvinhu zvine hutsi hwepamusoro hwemvura, senge simbi foils kana yakakosha mapolymer.
Pamusoro pezvo, magadzirirwo akakodzera anogona kudzikisira mhedzisiro yekunyorova uye kunyorova pane rigid-flex circuit board.Kuve nekuona nzvimbo yakakwana pakati pezvikamu uye zviteshi zvinobatsira kudzikisa mukana wekutama kwemwando uye kunoderedza njodzi yemapfupi maseketi.Pamusoro pezvo, kuita inodzorwa impedance dhizaini inogona kuwedzera kutendeseka kwechiratidzo uye kuderedza mhedzisiro yekunyorova-induced capacitance shanduko.
Kugara uchiyedzwa uye kutarisa kwakakoshawo kuchengetedza kuvimbika kweakaomesesa-flex edunhu mabhodhi.Kuyedzwa kwezvakatipoteredza, senge tembiricha uye humidity bhasikoro, kunogona kutevedzera mamiriro epasirese uye kuona kushaya simba mukugadzira kana kugadzira.Iyi bvunzo inogona kubatsira kuona chero kudzikisira kwekuita kana kutadza nekuda kwekutorwa kwehunyoro uye kutungamira gadziriso yeramangwana.
Muchidimbu,humidity uye unyoro zvinogona kukanganisa zvakanyanya kuita uye kuvimbika kweakaomesesa-flex circuit board.Kuvapo kwehunyoro kunogona kukonzera ngura, kuzvimba, delamination uye dimensional shanduko, zvichikonzera akasiyana ekushanda matambudziko.Nekudaro, mainjiniya nevagadziri vanogona kudzikisira mhedzisiro iyi kuburikidza nekushandiswa kwezvinhu zvakakodzera, machira ekudzivirira, akakodzera magadzirirwo ekufunga uye kuomarara kuyedzwa.Nekunzwisisa mhedzisiro yekunyorova uye hunyoro pamabhodhi edunhu-akaomarara uye nekushandisa nzira dzakasimba dzekudzikisa, zvigadzirwa zvemagetsi zvinogona kuramba zvichishanda zvakavimbika munzvimbo dzakasiyana siyana.
