Zenziwa njani iibhodi zesekethe eziqinileyo-flex?

Kule post blog, siza kuphonononga inkqubo yokwenziwa kweebhodi zesekethe eziqinileyo kwaye siqonde ukuba zenziwe njani.

Iibhodi zesekethe eziguquguqukayo, ezaziwa ngokuba ziibhodi zesekethe eziguquguqukayo (PCBs), zithandwa kushishino lwe-elektroniki ngenxa yokukwazi ukudibanisa iingenelo zeePCB eziqinileyo neziguquguqukayo.Ezi bhodi zibonelela ngezisombululo ezizodwa kwizicelo ezifuna ukuguquguquka kunye nokuqina.

Ukuqonda inkqubo yokwenziwa kweebhodi zeesekethe eziguquguqukayo, masiqale sixoxe ukuba ziphi.Iibhodi eziguquguqukayo eziguquguqukayo zesekethe zibandakanya i-PCB ene-multi-layer bhetyebhetye kunye noqhagamshelo oluqinileyo lwePCB.Olu kudibanisa lubavumela ukuba banikeze ukuguquguquka okuyimfuneko ngaphandle kokuncama ukunyaniseka kwesakhiwo esibonelelwa ngamapaneli aqinile.Ezi bhodi zifanelekile ukuba zisetyenziswe kumashishini ahlukeneyo, kuquka i-aerospace, unyango kunye neemoto, ukuze zisetyenziswe kwizixhobo ezifana ne-electronics wearable, implants yonyango kunye ne-automotive sensors.

Ngoku, makhe sihlolisise inkqubo yokwenziwa kweebhodi zesekethe eziqinileyo.Inkqubo yokwenziwa kwezi bhodi ibandakanya amanyathelo amaninzi, ukusuka kwinqanaba lokuyila ukuya kwindibano yokugqibela.Nanga amanyathelo aphambili abandakanyekayo:

1. Uyilo: Isigaba sokuyila siqala ngokudala ibhodi yesekethe yokucwangcisa, ngokuqwalasela imilo efunekayo, ubungakanani kunye nokusebenza.Abaqulunqi basebenzisa isoftware ekhethekileyo ukuyila iibhodi zeesekethe kunye nokumisela ukubekwa kwamacandelo kunye nomzila wokulandela umkhondo.

2. Ukukhetha izinto eziphathekayo: Ukukhetha izinto ezifanelekileyo kubalulekile ekwenzeni iibhodi eziguquguqukayo.Kubandakanya ukukhetha ii-substrates eziguquguqukayo (ezifana ne-polyimide) kunye nezixhobo eziqinileyo (ezifana ne-FR4) ezinokumelana noxinzelelo olufunekayo lomatshini kunye nokutshintsha kweqondo lokushisa.

3. Ukuvelisa i-substrate eguquguqukayo: I-substrate eguquguqukayo yenziwe ngendlela eyahlukileyo ngaphambi kokuba ihlanganiswe kwibhodi yesekethe e-rigid-flex.Oku kubandakanya ukusebenzisa i-conductive layer (ngokuqhelekileyo ubhedu) kwizinto ezikhethiweyo kwaye emva koko uyifake ukuze wenze iphethini yesiphaluka.

4. Ukwenziwa kweebhodi eziqinileyo: Kwakhona, iibhodi eziqinileyo zenziwe kusetyenziswa iindlela eziqhelekileyo zokuvelisa i-PCB.Oku kubandakanya iinkqubo ezifana nokugrumba imingxunya, ukusebenzisa iileya zobhedu, kunye ne-etching ukwenza i-circuitry efunekayo.

5. I-Lamination: Emva kokuba ibhodi eguquguqukayo kunye nebhodi eqinile ilungiselelwe, i-laminated kunye kusetyenziswa i-adhesive ekhethekileyo.Inkqubo ye-lamination iqinisekisa ubudlelwane obuqinileyo phakathi kweentlobo ezimbini zeebhodi kwaye ivumela ukuguquguquka kwiindawo ezithile.

6. Umfanekiso wepatheni yesekethe: Sebenzisa inkqubo ye-photolithography ukuze ubonise iipatheni zeesekethe zeebhodi eziguquguqukayo kunye neebhodi eziqinileyo kuluhlu lwangaphandle.Oku kubandakanya ukudlulisa ipateni efunekayo kwifilim ebonisa ifoto okanye umaleko wokuxhathisa.

7. I-Etching kunye ne-plating: Emva kokuba iphethini yesekethe ibonakaliswe, ubhedu oluvezwayo lukhutshwe, lushiya imikhondo yesekethe efunekayo.Emva koko, i-electroplating yenziwa ukuqinisa imikhondo yobhedu kunye nokubonelela nge-conductivity efunekayo.

8. Ukwemba kunye nendlela: Gcoba imingxuma kwibhodi yesekethe ukuze kufakwe icandelo kunye noqhagamshelo.Ukongezelela, umzila wenziwa ukwenza udibaniso oluyimfuneko phakathi kweengqimba ezahlukeneyo zebhodi yesekethe.

9. Indibano yecandelo: Emva kokuba ibhodi yesiphaluka iveliswe, iteknoloji yokunyuka kwendawo okanye iteknoloji ye-hole-hole isetyenziselwa ukufaka i-resistors, i-capacitors, iisekethe ezidibeneyo kunye nezinye izinto kwibhodi yesekethe e-rigid-flex.

10. Uvavanyo kunye noHlolo: Nje ukuba amacandelo athengiswe ebhodini, aphantsi kovavanyo olunzima kunye nenkqubo yokuhlola ukuqinisekisa ukuba asebenza kwaye ahlangabezane nemigangatho yomgangatho.Oku kubandakanya uvavanyo lombane, uhlolo olubonakalayo kunye nokuhlolwa kwe-automated optical.

11. Indibano yokugqibela kunye nokupakishwa: Inyathelo lokugqibela kukudibanisa ibhodi yesekethe engqongqo-flex kwimveliso oyifunayo okanye isixhobo.Oku kunokubandakanya amacandelo ongezelelweyo, izindlu kunye nokupakishwa.

Isishwankathelo

Inkqubo yokwenziwa kweebhodi zeesekethe eziqinileyo zibandakanya amanyathelo amaninzi anzima ukusuka kuyilo ukuya kwindibano yokugqibela.Inhlanganisela ekhethekileyo yezinto eziguquguqukayo kunye neziqinileyo zibonelela ngokuguquguquka okukhulu kunye nokuqina, okwenza ezi bhodi zilungele usetyenziso oluhlukeneyo.Njengoko itekhnoloji iqhubeka nokuhambela phambili, imfuno yeebhodi zesekethe eziguquguqukayo kulindeleke ukuba ikhule, kwaye ukuqonda iinkqubo zabo zokuvelisa kuye kwabaluleka kakhulu kubavelisi kunye neenjineli zoyilo.
