Isetyhula ye-2 yeFPC Flex yePCB yoHlalutyi lweInfrared yezoNyango

Isifundo: Isixhobo sonyango somhlalutyi we-infrared 2-layer flexible PCB board

Yazisa:

Iibhodi zePCB ezi-2 eziguquguqukayokuhlalutyi lwezixhobo zonyango lwe-infrared zizinto ezibalulekileyo ekusebenzeni ngokubanzi kunye nokusebenza kwesixhobo. Olu hlalutyo lwemeko luya kugxininisa kwimiba yobugcisa bemveliso, kubandakanywa ububanzi bomgca kunye nesithuba, ubukhulu bebhodi, ubukhulu bobhedu, i-aperture encinci, i-flame retardant grade, unyango lomphezulu, umbala we-solder mask, ukuqina, njl. kunye nezixhobo.

Uhlobo lwemveliso:

Ibhodi ye-PCB ene-2-layer eguquguqukayoLe mveliso yibhodi ye-PCB ene-2-layer flexible. Ezi phaneli zenzelwe ukuba zibe khaphukhaphu kwaye ziguquguquke, zizenze zilungele izicelo apho iipaneli kufuneka zihambelane nemo ethile okanye zingene kwiindawo ezixineneyo.

Iinkcukacha zobugcisa:

Ububanzi bomgca kunye nesithuba:Ububanzi bomgca webhodi yePCB kunye nemilinganiselo yendawo ibalulekile ekuqinisekiseni intembeko yophawu olufanelekileyo kunye nokuthembeka. Kulo mzekelo, ububanzi bomgca ngu-0.12mm kunye nomgca we-0.1mm, ukuqinisekisa ukuchaneka kokudluliselwa kwesignali.

Ubukhulu bebhodi:I-0.15mm ubukhulu bebhodi bumisela ukuguquguquka ngokubanzi kunye nokuqina kwe-PCB. Oku kuqwalasela kubalulekile ukuqinisekisa ukuba ibhodi inokumelana noxinzelelo oluhambelana nokugoba okanye ukugoba ngaphandle kokuchaphazela ukusebenza kwayo.

Ukutyeba kobhedu:Ubungqingqwa be-18um bobhedu bubonelela nge-conductivity efunekayo ukuhambisa imiqondiso kwiPCB. Olu ngqingqwa lukhethwe ngononophelo ukulungelelanisa i-conductivity kunye nokuguquguquka kwebhodi ngokubanzi.

Ubuncinci bedayamitha yomngxuma:Ubuncinane bomngxuma wedayamitha eyi-0.15mm ibhekisa kubungakanani bomngxuma obuncinane obunokugrunjwa kwiPCB. Oku kuchanekileyo kubalulekile ukulungiselela amacandelo kunye nokuqinisekisa uqhagamshelwano olufanelekileyo.

Ukuncipha komlilo:Ibanga elibuyisela idangatye lifikelela kwi-94V0, libonisa ukuba izinto zePCB zinokumelana nomlilo ophezulu kwaye zizicima. Oku kubalulekile kwingqwalasela yokhuseleko, ngakumbi kwiinkqubo zezixhobo zonyango.

Unyango lomphezulu:Unyango lwegolide oluntywilisiweyo lune-conductivity egqwesileyo kunye nokuxhathisa umhlwa. Iqinisekisa uqhagamshelo oluthembekileyo kunye nokuzinza kwexesha elide lePCB.

Imibala Yemaski yeSolder:Umbala ophuzi wokumelana ne-welding ibonisa izinto ezithile okanye iingubo ezisetyenziselwa inkqubo ye-welding. Umbala omthubi unokukhethwa ngenxa yezizathu zobuhle okanye ukwahlula indawo ethile kwi-PCB.

Ukuqina:PCBs ziyilwe kunye bhetyebhetye engqondweni kwaye indibaniselwano yemathiriyeli ingasetyenziselwa ukufikelela ukuqina olufunekayo. Kule meko, izinto ezifana ne-PI (Polyimide) kunye ne-FR4 (i-Flame Retardant 4) ingasetyenziselwa ukubonelela ngebhalansi efunekayo phakathi kokuguquguquka kunye nokuqina.

Usetyenziso kunye neZixhobo:Ibhodi ye-PCB eguquguqukayo e-2 eyenzelwe ngokukodwa izixhobo zonyango zomhlalutyi we-infrared. Ezi zixhobo zisebenzisa itekhnoloji ye-infrared ukuhlalutya kunye nokulinganisa iiparamitha ezahlukeneyo kwiisampulu zonyango. I-PCB eguquguqukayo yenza isixhobo sihlangane, sikhaphukhaphu kwaye siyilwe ngokwe-ergonomically kuzo zombini izicelo zonyango eziphathwayo nezimileyo.
