Imigangatho yeshishini lokwenziwa kwebhodi engqongqo-flex

Ngaba kukho nayiphi na imigangatho yoshishino ethile ekufuneka ilandelwe ngabavelisi xa kufikwa kwimveliso yePCB eqinileyo? Kule post yebhlog, siza kuphonononga lo mbuzo kwaye sijonge ukubaluleka kwemigangatho yoshishino kule ndawo.

Xa kuziwa kwibhodi yesekethe eprintiweyo (PCB) yokuvelisa, kubalulekile ukuthobela imigangatho yoshishino ukuqinisekisa ukuveliswa kweemveliso ezikumgangatho ophezulu. Kwiminyaka yakutshanje, ii-PCB eziguquguqukayo zifumene ukuthandwa ngenxa yokuguquguquka kwazo kunye nokuqina.

Ukuze uqonde ingqikelelo yemigangatho yoshishino lokwenziwa kwe-PCB engqongqo, kufuneka uqale uqonde iziseko ze-PCB eguquguqukayo. I-Rigid-flex PCB yindibaniselwano yee-substrates eziqinileyo neziguquguqukayo ezidityanisiweyo ukwenza ibhodi yesekethe enye.Ezi ntlobo zePCB zibonelela ngeenzuzo ezininzi, ezinjengobunzima obuncitshisiweyo, ukuthembeka okuphuculweyo, kunye nokuguquguquka koyilo oluphuculweyo. Ngokuqhelekileyo zisetyenziswa kumashishini afana ne-aerospace, izixhobo zonyango, kunye nombane wabathengi.

Ngelixa kungekho migangatho yoshishino ethile engqalileyoeqinile-flex ukwenziwa PCB, kukho imigangatho eliqela ngokubanzi elawula yonke inkqubo yokwenziwa kwePCB.Le migangatho isebenza kuzo zonke iindidi zee-PCB kwaye igubungela yonke imiba yenkqubo yokuvelisa, kubandakanywa ukuyila, ukuvelisa, ukuhlanganisa kunye nokuvavanya. Eminye yemigangatho evunywe ngokubanzi lishishini le-PCB iquka imigangatho ye-International Electrotechnical Commission (IEC), imigangatho yeZiko leeSekethe eziprintiweyo (IPC), kunye nomyalelo wokuThintelwa kwezinto ezinobungozi (RoHS).

I-IEC ngumbutho wehlabathi ophuhlisa kwaye upapashe imigangatho yamazwe ngamazwe yobugcisa bombane nombane, ukuphuhlisa izikhokelo ezisebenza jikelele kuzo zonke iinkqubo zokwenziwa kwePCB.Ezi zikhokelo zibandakanya uluhlu olubanzi lwemiba, kubandakanywa ukucaciswa koyilo, ukukhethwa kwezinto eziphathekayo, iinkqubo zokuvelisa kunye nokulawula umgangatho. Ukuthobela le migangatho kuqinisekisa ukuba iiPCBs ziyahlangabezana nomgangatho ofanayo kunye neemfuno zokhuseleko.

Ngokunjalo, i-IPC, umbutho owaziwayo wokumisela imigangatho kushishino lombane, ubonelela ngezikhokelo ezibalulekileyo kuzo zonke iinkalo zokwenziwa kwePCB.Imigangatho ye-IPC igubungela izihloko ezifana nemigaqo yoyilo, iimfuno zemathiriyeli, iinkqubo zokuvelisa, iinkqubo zovavanyo, kunye neendlela zokwamkelwa. Le migangatho ibonelela abavelisi ngeembekiselo ezixabisekileyo zokuqinisekisa ukuthembeka kunye nokusebenza kweemveliso zabo.

Ukongeza kule migangatho jikelele, abavelisi kufuneka bathathele ingqalelo iimfuno ezithile zoshishino xa besenza iiPCBs eziguquguqukayo.Amashishini afana ne-aerospace kunye nezixhobo zonyango zihlala zineenkcazo ezizodwa ngenxa yobume obubalulekileyo bezicelo zabo. Umzekelo, iiPCB ze-aerospace kufuneka zihlangabezane nezikhokelo ezingqongqo ezinxulumene nokuthembeka, ukumelana nobushushu, kunye nokumelana nokungcangcazela. Ngokunjalo, ii-PCB zezixhobo zonyango kufuneka zihambelane nemigaqo yokuhambelana nebhayoloji kunye nokuvala inzala.

Abavelisi abaninzi bakwalandela imiyalelo ye-RoHS, ethintela ukusetyenziswa kwezinto eziyingozi kwizixhobo zombane neze-elektroniki.Lo myalelo uthintela ubukho bezinto ezifana nelothe, imekyuri, i-cadmium kunye nezinto ezithile ezibuyiswa ngamadangatye. Ukuthotyelwa kwe-RoHS akuqinisekisi kuphela ukhuseleko lwabasebenzisi bokugqibela, kodwa kubonisa ukuzinikela kuxanduva lokusingqongileyo.

Ngelixa le migangatho jikelele kunye neshishini elithile libonelela ngesikhokelo esixabisekileyo sokwenziwa kwePCB, kubalulekile ukuqaphela ukuba ayibopheleli ngokusemthethweni.Nangona kunjalo, ukubambelela kule migangatho kubalulekile ngenxa yezizathu ezininzi. Okokuqala, ukulandela imigangatho kuvumela abavelisi ukuba bavelise iimveliso ezikumgangatho ophezulu ezihlangabezana nokulindelwe ngabathengi. Okwesibini, iqinisekisa ukuhambelana kwinkqubo yokuvelisa, ngaloo ndlela ukwandisa ukusebenza kakuhle kunye nokunciphisa iindleko. Ekugqibeleni, ukubambelela kwimigangatho kwandisa isidima somenzi kunye nokuthembeka kwishishini.

Ukongeza kokubambelela kwimigangatho yoshishino, abavelisi banokuphumeza ainkqubo yolawulo lomgangatho (QMS)ukuphucula ngakumbi iinkqubo zabo zokwenziwa kwePCB eziguquguqukayo.Iisistim zolawulo lomgangatho zinceda imibutho ilungelelanise imisebenzi kwaye isoloko ihlangabezana neemfuno zabathengi. Ibonelela ngesakhelo sokuchonga nokusombulula iingxaki, ukuphucula ulawulo lwenkqubo, kunye nokuqinisekisa uphuculo oluqhubekayo.

Isishwankathelo,Ngelixa kungekho migangatho yoshishino ethe ngqo kwimveliso yePCB eguquguqukayo, kukho imigangatho ethile jikelele kunye neshishini elithile ekufuneka abavelisi babambelele kuyo. Le migangatho igubungela yonke imiba yokwenziwa kwePCB, iqinisekisa ukuveliswa kwemveliso ekumgangatho ophezulu, ethembekileyo. Ngokulandela le migangatho, abavelisi banokuphucula ukusebenza kwemveliso, ukuhlangabezana nokulindela kwabathengi, kwaye babe ngumdlali othembekileyo kumashishini.
