Iingcingo kunye nokunyuswa kwecandelo leebhodi zesekethe eziguquguqukayo eziprintiweyo (FPCB)

Kule post yebhlog, siza kuphonononga imiba ephambili yoyilo lweFPCB kwaye sibonelele ngezimvo ezixabisekileyo malunga nendlela yokuyila ngokufanelekileyo umzila kunye nokunyuswa kwecandelo.

Iibhodi zeesekethe eziprintiweyo eziguquguqukayo (FPCB) ziye zaguqula imboni ye-elektroniki kunye nokuguquguquka okungenakulinganiswa kunye nokuguquguquka. Banikezela ngeenzuzo ezininzi kwiibhodi zesekethe eziqinileyo, kubandakanya izinto ezincinci zefom, ubunzima obuncitshisiweyo kunye nokuqina okukhulu. Nangona kunjalo, xa uyila i-wiring kunye nokunyuswa kwecandelo le-FPCB, izinto ezithile kufuneka ziqwalaselwe ngononophelo ukuze kuqinisekiswe ukusebenza kakuhle kunye nokuthembeka.

1. Qonda iimpawu ezizodwa zeFPCB

Ngaphambi kokuba singene kwinkqubo yoyilo, kubalulekile ukuqonda iimpawu ezizodwa zeFPCBs. Ngokungafaniyo neebhodi zesekethe eziqinileyo, ii-FPCBs zibhetyebhetye kwaye zinokugotshwa kwaye zijijelwe ukuze zilungele izinto ezahlukeneyo zefomu. Ukongeza, zibandakanya umaleko obhityileyo wezinto zokuqhuba (ngokuqhelekileyo ubhedu) ezifakwe phakathi kweengqimba zezinto eziguquguqukayo zokugquma. Ezi mpawu zinefuthe kwingqwalasela yoyilo kunye nobuchule obusetyenziswa kwikhebhula kunye nofakelo lwamacandelo.

2. Cwangcisa ukuma kwesekethe

Isinyathelo sokuqala ekuyileni i-FPCB i-wiring kunye nokunyuswa kwecandelo kukucwangcisa ngononophelo ucwangciso lwesekethe. Amalungu esikhundla, izihlanganisi, kunye nemikhondo ukwandisa imfezeko yomqondiso kunye nokunciphisa ingxolo yombane. Kuyacetyiswa ukuba wenze ischematics kwaye ulinganise ukusebenza usebenzisa isoftware ekhethekileyo ngaphambi kokuba uqhubeke noyilo lokwenyani.

3. Qwalasela ukuguquguquka kunye neradiyasi yokugoba

Kuba ii-FPCBs ziyilelwe ukuba zibe bhetyebhetye, kubalulekile ukuqwalasela iradiyasi yokugoba ngexesha loyilo. Izixhobo kunye neetrayisi kufuneka zibekwe ngokucwangcisiweyo ukuphepha ukugxininiswa koxinzelelo olunokubangela ukuphuka okanye ukungaphumeleli. Kunconywa ukugcina i-radius encinci yokugoba echazwe ngumvelisi weFPCB ukuqinisekisa ubude bebhodi yesekethe.

4. Ukwandisa imfezeko yomqondiso

Ukunyaniseka komqondiso ofanelekileyo kubalulekile ekusebenzeni okuthembekileyo kweFPCBs. Ukufezekisa oku, uphazamiseko lwesignali, crosstalk kunye nokukhutshwa kwe-electromagnetic kufuneka kuncitshiswe. Ukusebenzisa inqwelo-moya ephantsi komhlaba, ukukhusela, kunye nokuhamba ngononophelo kunokuphucula kakhulu imfezeko yomqondiso. Ukongeza, imiqondiso enesantya esiphezulu kufuneka ilawule umkhondo we-impedance ukunciphisa ukuncipha komqondiso.

5. Khetha amacandelo afanelekileyo

Ukukhetha amacandelo afanelekileyo kuyilo lwakho lweFPCB kubalulekile ekuqinisekiseni ukusebenza kakuhle kunye nokuthembeka. Qwalasela izinto ezifana nobukhulu, ubunzima, amandla asetyenziswayo, kunye noluhlu lobushushu xa ukhetha izinto. Ukongezelela, amacandelo kufuneka ahambelane neenkqubo zokuvelisa ze-FPCB ezifana neteknoloji ye-surface Mount (SMT) okanye ngeteknoloji ye-hole (THT).

6. Ulawulo lobushushu

Njengayo nayiphi na inkqubo yombane, ulawulo lobushushu lubalulekile kuyilo lweFPCB. Ii-FPCBs zinokuvelisa ubushushu ngexesha lokusebenza, ngakumbi xa usebenzisa izinto ezisebenza ngamandla. Qinisekisa ukupholisa okwaneleyo ngokusebenzisa iisinki ezishushu, i-thermal vias, okanye ukuyila uyilo lwebhodi ngendlela ekhuthaza ukuhamba komoya okusebenzayo. Uhlalutyo lwe-Thermal kunye nokulinganisa kunokunceda ukuchonga iindawo ezinokuthi zishushu kwaye ulungise uyilo ngokufanelekileyo.

7. Landela izikhokelo zoYilo lweManufacturability (DFM).

Ukuqinisekisa utshintsho olungenamagingxi-gingxi ukusuka kuyilo ukuya kwimveliso, izikhokelo zeFPCB-specific design for production (DFM) kufuneka zilandelwe. Ezi zikhokelo zijongana nemiba efana nobubanzi bomkhondo obuncinci, isithuba, kunye nezangqa zonyaka ukuqinisekisa ukwenziwa. Sebenza ngokusondeleyo nabavelisi ngexesha lesigaba soyilo ukusombulula nayiphi na imiba enokubakho kunye nokwandisa uyilo lwemveliso esebenzayo.

8. Iprototype kunye novavanyo

Emva kokuba uyilo lokuqala lugqityiwe, kucetyiswa kakhulu ukuvelisa iprototype yokuvavanya kunye neenjongo zokuqinisekisa. Uvavanyo kufuneka lubandakanye ukusebenza, imfezeko yomqondiso, ukusebenza kwe-thermal, kunye nokuhambelana neemeko zokusetyenziswa ezicetywayo. Chonga iziphene ezinokuthi zibe kho okanye iindawo zokuphucula kwaye uphinda uyilo ngokufanelekileyo ukufezekisa umsebenzi ofunekayo.

Isishwankathelo

Ukuyila iibhodi zesekethe eziguquguqukayo eziprintwayo ukulungiselela indlela kunye nokunyuswa kwecandelo kufuna uqwalaselo olucokisekileyo lwemiba eyahlukeneyo eyahlukileyo kwezi bhodi ezibhetyebhetye. Uyilo olusebenzayo noluqinileyo lweFPCB lunokuqinisekiswa ngokuqonda iimpawu, ukucwangciswa koyilo, ukulungelelanisa ingqibelelo yomqondiso, ukukhetha amacandelo afanelekileyo, ukulawula imiba yokushisa, ukulandela izikhokelo zeDFM, kunye nokwenza uvavanyo olucokisekileyo. Ukwamkela obu buchwepheshe kuya kwenza ukuba iinjineli ziqonde amandla apheleleyo e-FPCBs ekudaleni izixhobo zombane ezitsha kunye nezisika umva.
