Ngaba ukhe wazibuza ukuba ungavavanya njani ukusebenza kwebhodi yesekethe engqongqo? Musa ukuthandabuza kwakhona! Kule post blog, siza kuphonononga iindlela ezahlukeneyo kunye nezicwangciso zokuqinisekisa ukusebenza ngokufanelekileyo kweebhodi zesekethe eziqinileyo. Nokuba ungumchwephesha onamava okanye umtsha ebaleni, ezi ngcebiso kunye nobuchule ziya kukunceda ukuvavanya ngokufanelekileyo ukusebenza kweebhodi zesekethe eziqinileyo.

Ngaphambi kokuba singene kwiindlela ezahlukeneyo zovavanyo, masichaze ngokufutshane ukuba yintoni ibhodi yesekethe eqinileyo. Iibhodi zesekethe eziguquguqukayo ziyindibaniselwano yeebhodi zesekethe eziqinileyo kunye neziguquguqukayo, ukudala uyilo oluxubileyo olunikezela ngeyona nto ibalaseleyo yehlabathi. Ezi bhodi zisetyenziswa ngokuqhelekileyo kwizicelo apho indawo iyancipha kwaye ukuqina kunye nokuthembeka kubaluleke kakhulu.

Ngoku, masiqhubele phambili kwisihloko esiphambili seli nqaku - ukuvavanya ukusebenza kweebhodi zesekethe eziqinileyo. Kukho iimvavanyo ezininzi onokuzenza ukuze uqinisekise ukuba ibhodi yakho isebenza njengoko kulindelekile. Makhe sihlolisise ezinye zezi mvavanyo ngokweenkcukacha.

1. Ukuhlolwa okubonakalayo kweebhodi zesekethe eziguquguqukayo eziqinileyo:

Isinyathelo sokuqala ekuvavanyeni ukusebenza kwebhodi yesekethe ye-rigid-flex kukujonga ngokubonakalayo nawuphi na umonakalo womzimba okanye iziphene zokuvelisa. Khangela naziphi na iimpawu zokuqhekeka, ukuphuka, imiba ye-welding okanye izinto ezingaqhelekanga. Eli linyathelo lokuqala elibalulekileyo ekuchongeni nayiphi na imiba ebonakalayo enokuchaphazela ukusebenza ngokubanzi kwebhodi.

2. Uvavanyo oluqhubekayo iibhodi pcb bhetyebhetye:

Uvavanyo oluqhubekayo lwenziwa ukujonga ukuba ukudibaniswa kombane kwibhodi yesekethe kuhambelana. Ukusebenzisa i-multimeter, unokukhawuleza unqume ukuba kukho ikhefu okanye uvule kwi-trace conductive. Ngokuphonononga iindawo zonxibelelwano ezahlukeneyo, unokuqinisekisa ukuba isekethe igqityiwe kwaye iimpawu zihamba ngokuchanekileyo.

3. Uvavanyo lwe-impedance kwiibhodi eziguquguqukayo eziqinileyo:

Uvavanyo lwe-impedance lubalulekile ekuqinisekiseni ukuba amaxabiso e-impedance of trace kwibhodi yesekethe angaphakathi kwemida echaziweyo. Olu vavanyo luqinisekisa ukuba umqondiso awuchatshazelwa kuko nakuphi na ukungahambelani kwe-impedance, enokuthi ngenye indlela ibangele imiba yemfezeko yomqondiso.

4. Uvavanyo olusebenzayo lweebhodi zesekethe eziguquguqukayo eziqinileyo:

Uvavanyo olusebenzayo lubandakanya ukuqinisekiswa kokusebenza kwebhodi yesekethe ngokuvavanya imisebenzi yayo eyahlukeneyo. Oku kunokubandakanya uvavanyo lwamagalelo kunye neziphumo, ukuqhuba iinkqubo ezithile okanye ikhowudi, kunye nokulinganisa iimeko zobomi bokwenyani ukuqinisekisa ukuba ibhodi isebenza njengoko kulindelekile.

5. Uvavanyo lokusingqongileyo kwibhodi yesekethe ye-flex flex pcb:

Iibhodi zesekethe ezingqongqo-flex zihlala zibonakaliswe kwiimeko ezahlukeneyo zokusingqongileyo. Ke ngoko, uvavanyo lokusingqongileyo luyimfuneko ukuvavanya ukusebenza kweebhodi zeesekethe phantsi kweemeko ezahlukeneyo ezifana nobushushu, ukufuma, ukungcangcazela, okanye uxinzelelo lobushushu. Olu vavanyo lunceda ukuqinisekisa ukuba ibhodi inokumelana nemeko yokusebenza elindelekileyo ngaphandle kokuthotywa kokusebenza.

6. Uvavanyo lwengqibelelo yomqondiso kwiibhodi zesekethe eziguquguqukayo ze-ingid:

Uvavanyo lwengqibelelo yomqondiso lwenziwa ukuqinisekisa ukuba umqondiso uhanjiswa ngebhodi yesiphaluka ngaphandle kokuphazamiseka okanye ukuphazamiseka. Uvavanyo lubandakanya ukuhlalutya umgangatho wesignali kunye neeparitha zokulinganisa ezifana ne-crosstalk, i-jitter kunye ne-eye diagram ukuqinisekisa ukusebenza kakuhle.
Ukongeza kwezi mvavanyo ezithile, kubalulekile ukulandela iindlela ezifanelekileyo ngexesha loyilo kunye nezigaba zokuvelisa ukuqinisekisa ithuba eliphezulu lokufumana ibhodi esebenza kakuhle e-rigid-flex. Oku kubandakanya uphononongo olucokisekileyo loyilo, ukhetho olufanelekileyo lwemathiriyeli, kunye nokungaguquguqukiukuhlolwa komgangatho ngexesha lokuvelisa.

Isishwankathelo:

Ukuvavanya ukusebenza kwebhodi yesekethe ye-rigid-flex linyathelo elibalulekileyo ekuqinisekiseni ukusebenza kwayo ngokufanelekileyo. Ngokuhlola okubonwayo, uvavanyo oluqhubekayo, uvavanyo lwe-impedance, uvavanyo olusebenzayo, uvavanyo lokusingqongileyo, kunye novavanyo lwengqibelelo yomqondiso, unokuchonga kunye nokusombulula nayiphi na imiba enokuthi ichaphazele ukusebenza kwebhodi yakho. Ngokulandela ezi ndlela zokuvavanya kunye nezenzo ezilungileyo, unokuba nentembelo ekusebenzeni kunye nokuthembeka kweebhodi zakho zesekethe eziqinileyo.
