Kwihlabathi le-elektroniki, imfuno yeebhodi zesekethe eziprintiweyo eziphezulu (PCBs) ikhokelele ekuveleni koyilo lweRigid-Flex PCB. Ezi bhodi zobuchule zidibanisa ezona mpawu zibalaseleyo zeePCBs eziqinileyo neziguquguqukayo, zibonelela ngeenzuzo ezizodwa malunga nokonga indawo, ukunciphisa ubunzima, kunye nokuthembeka okuphuculweyo. Nangona kunjalo, enye inkalo ebalulekileyo ehlala ingahoywa kwinkqubo yoyilo kukukhetha i-soldermask efanelekileyo. Eli nqaku liza kuhlolisisa indlela yokukhetha i-soldermask efanelekileyo yoyilo lwe-Rigid-Flex PCB, ngokuqwalasela izinto ezifana neempawu eziphathekayo, ukuhambelana nenkqubo yokuvelisa i-PCB, kunye nezakhono ezithile ze-Rigid-Flex PCBs.
Ukwazi iRigid-Flex PCB Design
I-Rigid-Flex PCBs yi-hybrid yobuchwepheshe besekethe eqinile kwaye eguquguqukayo, evumela ukuyila okuntsokothileyo okunokugoba kunye nokuguquguquka ngaphandle kokunciphisa ukusebenza. I-stackup yomaleko kwi-Rigid-Flex PCBs idla ngokuqulatha iileya ezininzi zezinto eziqinileyo neziguquguqukayo, ezinokuthi zilungelelaniswe ukuhlangabezana neemfuno ezithile zesicelo. Oku kuguquguquka kwenza ukuba iiRigid-Flex PCBs zilungele ukusetyenziswa kwi-aerospace, izixhobo zonyango, kunye nombane wabathengi, apho isithuba kunye nobunzima zizinto ezibalulekileyo.
Indima yeSoldermask kwiRigid-Flex PCB Design
I-Soldermask ngumaleko okhuselayo osetyenziswa kumphezulu we-PCB ukuthintela ukudityaniswa kwe-solder, ukukhusela kumonakalo wokusingqongileyo, kunye nokuphucula ukuqina kwebhodi kukonke. Kwi-Rigid-Flex PCB uyilo, i-soldermask kufuneka ifake iimpawu ezizodwa zamacandelo aqinileyo kunye aguquguqukayo. Kulapho ukhetho lwempahla ye-soldermask luba lubalulekileyo.
Iimpawu zezinto eziphathekayo ekufuneka ziqwalaselwe
Xa ukhetha i-soldermask ye-Rigid-Flex PCB, kubalulekile ukukhetha izinto ezinokumelana nokuphambuka koomatshini kunye noxinzelelo lokusingqongileyo. Ezi mpawu zilandelayo kufuneka ziqwalaselwe:
Ukuchasa ukuPhambuka:I-soldermask kufuneka ikwazi ukunyamezela ukugoba kunye nokuguquka okwenzeka kumacandelo aguquguqukayo e-PCB. Isikrini soshicilelo oluguquguqukayo lwe-photosensitive uphuhliso lwe-inki ye-soldermask lukhetho oluhle kakhulu, njengoko luyilelwe ukugcina ingqibelelo phantsi koxinzelelo lomatshini.
Ukumelana neWelding:I-soldermask kufuneka inike umqobo oqinileyo ngokuchasene ne-solder ngexesha lenkqubo yendibano. Oku kuqinisekisa ukuba i-solder ayingeni kwiindawo apho inokubangela iisekethe ezimfutshane okanye eminye imiba.
Ukuxhathisa ukufuma:Ngenxa yokuba ii-PCB ze-Rigid-Flex zihlala zisetyenziswa kwiindawo apho ukuvezwa kokunyakama kuyinkxalabo, i-soldermask kufuneka ibonelele ukuxhathisa ukufuma okugqwesileyo ukuthintela ukubola kunye nokuthotywa kwesekethe engaphantsi.
Ukumelana noNgcoliseko:I-soldermask kufuneka ikhusele ngokuchasene nezinto ezingcolileyo ezinokuchaphazela ukusebenza kwe-PCB. Oku kubaluleke kakhulu kwizicelo apho i-PCB inokuthi ibe sesichengeni sothuli, iikhemikhali, okanye ezinye izinto ezingcolisayo.
Ukuhambelana neNkqubo yokuVelisa iPCB
Enye into ebalulekileyo ekukhetheni i-soldermask efanelekileyo kukuhambelana kwayo nenkqubo yokuvelisa i-PCB. I-Rigid-Flex PCBs ithatha amanyathelo ahlukeneyo okuvelisa, kubandakanya i-lamination, i-etching, kunye ne-soldering. I-soldermask kufuneka ikwazi ukumelana nezi nkqubo ngaphandle kokuthotywa okanye ukulahlekelwa iimpawu zayo zokukhusela.
Lamination:I-soldermask kufuneka ihambelane nenkqubo ye-lamination esetyenziselwa ukudibanisa iileyile eziqinileyo kunye neziguquguqukayo. Akufunekanga idilize okanye ixobule ngeli nyathelo libalulekileyo.
Etching:I-soldermask kufuneka ikwazi ukumelana nenkqubo yokudibanisa esetyenziselwa ukudala iipatheni zesekethe. Kufuneka inikeze ukhuseleko olwaneleyo kwimikhondo yobhedu engaphantsi ngelixa ivumela ukukrolwa okuchanekileyo.
Ukusoda:I-soldermask kufuneka ikwazi ukunyamezela amaqondo obushushu aphezulu ahambelana ne-soldering ngaphandle kokunyibilika okanye ukuguqulwa. Oku kubaluleke ngakumbi kumacandelo aguquguqukayo, anokuthi achaphazeleke ngakumbi kumonakalo wobushushu.
I-Rigid-Flex ye-PCB yekhono
Amandla eRigid-Flex PCBs adlulela ngaphaya kwesakhiwo sazo somzimba. Banokuxhasa uyilo oluntsonkothileyo olunemigangatho emininzi, evumela umgaqo ontsonkothileyo kunye nokubekwa kwecandelo. Xa ukhetha i-soldermask, kubalulekile ukuqwalasela indlela eya kusebenzisana ngayo nezi zakhono. I-soldermask ayifanele ithintele ukusebenza kwePCB kodwa kunokonyusa ukusebenza kwayo.
