Ukuvelisa itekhnoloji yeebhodi zesekethe eziqinileyo-flex

Kule posi yebhlog, siza kuphonononga itekhnoloji yokuvelisa eyohlukeneyo esetyenziselwa ukuvelisa ii-PCB eziguquguqukayo kwaye sijonge ukubaluleka kwazo kwinkqubo yokuvelisa.

Iibhodi zesekethe eziprintiweyo ezingqongqo (PCBs) ziya zithandwa kakhulu kushishino lwe-elektroniki ngenxa yeenzuzo zazo ezininzi ngaphezulu kweePCB zemveli ezingqongqo okanye ezibhetyebhetye. Ezi bhodi zintsha zidibanisa ukuguquguquka kunye nokuqina, zizenza zilungele usetyenziso apho indawo incinyiwe kwaye ukuqina kubalulekile. Ukuvelisa iibhodi ze-rigid-flex zibandakanya iintlobo ezahlukeneyo zetekhnoloji zokuqinisekisa ukwenziwa ngokufanelekileyo kunye nokuhlanganisa iibhodi zeesekethe.

1. Iingqwalasela zoyilo kunye nokukhetha imathiriyeli:

Phambi kokuba uqalise ukujonga itekhnoloji yokuvelisa, uyilo kunye nemiba yemathiriyeli yeePCBs eziguquguqukayo kufuneka ziqwalaselwe. Uyilo kufuneka lucwangciswe ngononophelo, kuthathelwe ingqalelo isicelo esicetywa yibhodi, iimfuno zokuguquguquka, kunye nenani leeleya ezifunekayo. Ukukhethwa kwezinto eziphathekayo kubaluleke ngokulinganayo njengoko kuchaphazela ukusebenza ngokubanzi kunye nokuthembeka kwebhodi. Ukumisela indibaniselwano efanelekileyo yee-substrates eziguquguqukayo neziqinileyo, i-adhesives, kunye nezixhobo zokuqhuba zibalulekile ekuqinisekiseni iziphumo ezifunwayo.

2. Ukwenziwa kweesekethe eziguquguqukayo:

Inkqubo yokuvelisa i-flex circuit ibandakanya ukudala iileyile eziguquguqukayo usebenzisa i-polyimide okanye ifilimu ye-polyester njenge-substrate. Ifilimu ithatha uchungechunge lweenkqubo ezinjengokucoca, ukugquma, ukucinga, i-etching kunye ne-electroplating ukwenza iphethini yesekethe efunekayo. Umaleko oguquguqukayo ke udityaniswe kunye nomaleko oqinileyo ukwenza i-PCB epheleleyo engqongqo-eguquguqukayo.

3. Ukwenziwa kweesekethe eziqinileyo:

Inxalenye engqongqo ye-PCB eguquguqukayo eguquguqukayo yenziwa kusetyenziswa ubuchule bokuvelisa be-PCB bemveli. Oku kubandakanya iinkqubo ezinjengokucoca, ukuthwebula imifanekiso, ukukrolwa kunye nokucwenga kweelaminates eziqinileyo. Umaleko oqinileyo ke ulungelelaniswa kwaye ubotshwe kuluhlu oluguquguqukayo usebenzisa i-adhesive ekhethekileyo.

4. Ukwemba kunye nokucwenga:

Emva kokuba iisekethe eziguquguqukayo kunye neziqinileyo zenziwe, isinyathelo esilandelayo kukubhoba imingxuma ukuvumela ukubekwa kwecandelo kunye nokudibanisa kombane. Ukugrumba imingxunya kwi-PCB eguquguqukayo engqongqo kufuna indawo echanekileyo ukuqinisekisa ukuba imingxuma kwindawo eguquguqukayo kunye neendawo eziqinileyo zilungelelanisiwe. Emva kokuba inkqubo yokugaya igqityiwe, imingxuma ifakwe kwizinto eziphathekayo ukuseka ukudibanisa kombane phakathi kweengqimba ezahlukeneyo.

5. Udibaniso lwamacandelo:

INdibano yamacandelo kwii-PCB eziguquguqukayo zinokuba ngumngeni ngenxa yokudityaniswa kwezinto eziguquguqukayo neziqinileyo. Itekhnoloji yemveli yokunyuka komphezulu (SMT) isetyenziselwa iindawo eziqinileyo, ngelixa iitekhnoloji ezithile ezifana ne-flex bonding kunye ne-flip-chip bonding zisetyenziselwa iindawo eziguquguqukayo. Ezi zixhobo zifuna abaqhubi abanezakhono kunye nezixhobo ezikhethekileyo zokuqinisekisa ukuba amacandelo afakwe ngokuchanekileyo ngaphandle kokubangela naluphi na uxinzelelo kwiindawo eziguquguqukayo.

6. Uvavanyo nokuhlolwa:

Ukuqinisekisa umgangatho kunye nokuthembeka kweebhodi ze-rigid-flex, uvavanyo olunzima kunye neenkqubo zokuhlola ziyafuneka. Yenza iimvavanyo ezahlukeneyo ezifana nokuvavanya ukuqhubeka kombane, uhlalutyo lwengqibelelo yomqondiso, ukukhwela ibhayisekile eshushu kunye novavanyo lokungcangcazela ukuvavanya amandla okusebenza ebhodi yesekethe. Ukongezelela, yenza uhlolo olucokisekileyo lokujonga ukujonga naziphi na iziphene okanye iziphazamiso ezinokuchaphazela ukusebenza kwebhodi.

7. Ukugqitywa kokugqibela:

Inyathelo lokugqibela ekwenzeni i-PCB eqinileyo kukusebenzisa i-coating yokukhusela ukukhusela i-circuitry kwizinto ezisingqongileyo ezifana nokufuma, uthuli, kunye nokuguquguquka kweqondo lokushisa. Iingubo zikwadlala indima ebalulekileyo ekwandiseni ukuqina kunye nokuchasana kwebhodi.

Isishwankathelo

Ukuvelisa iibhodi ezilukhuni-flex zifuna indibaniselwano yeendlela ezikhethekileyo zokuvelisa kunye nokuqwalaselwa ngokucophelela. Ukususela kuyilo kunye nokukhethwa kwezinto eziphathekayo kwimveliso, indibano yecandelo, uvavanyo kunye nokugqiba, isinyathelo ngasinye sibalulekile ukuqinisekisa ukusebenza kunye nokuphila ixesha elide kwebhodi yakho yesiphaluka. Njengoko ishishini le-elektroniki liqhubeka nokuhambela phambili, itekhnoloji yokuvelisa ephucukileyo nesebenzayo kulindeleke ukuba ikhuthaze ngakumbi uphuhliso lweebhodi eziguquguqukayo, zivule amathuba amatsha okusetyenziswa kwazo kwiinkqubo ezahlukeneyo zokusika.
