I-4-Layer PCB Stackups yokuGwanya ukuChaneka kunye noMgangatho woMngxuma woDonga : Iingcebiso zeNgcali yaseCapel

Yazisa:

Xa kuveliswa iibhodi zeesekethe eziprintiweyo (PCBs), ukuqinisekisa ukuchaneka kokomba kunye nomgangatho wodonga lomngxuma kwi-stack ye-PCB ye-4-layer ibaluleke kakhulu ekusebenzeni ngokubanzi kunye nokuthembeka kwesixhobo sombane.I-Capel yinkampani ehamba phambili kunye ne-15 iminyaka yamava kwishishini le-PCB, kunye nokulawula umgangatho njengento ephambili ekugxilwe kuyo.Le bhlog ijolise ekuboneleleni ngengqiqo exabisekileyo malunga nendlela yokufezekisa ukuchaneka okungenakulinganiswa kunye nomgangatho wodonga lomngxuma kwi-4-layer PCB stack-up, ngelixa igxininisa ubuchule be-Capel kunye nezisombululo ezithembekileyo ze-PCB.

1. Ukubaluleka kokuchaneka kokomba kunye nomgangatho wodonga lomngxuma kwi-4-layer PCB stack-up:

Ukuchaneka kokugaya kunye nomgangatho wodonga lomngxuma zizinto eziphambili ezichaphazela ngokuthe ngqo ukusebenza kwe-4-layer PCB stack. Ukuchaneka kakubi kokomba kunokukhokelela ekungalungelelaniseni icandelo, imiba ye-impedance, kunye nemiba yengqibelelo yomqondiso. Ngokufanayo, umgangatho onganeleyo wodonga lomngxuma unokuchaphazela ukusebenza kwe-plated ngokusebenzisa umngxuma (PTH) ukudibanisa, okukhokelela kwimicimbi yokuthembeka kunye nokunciphisa ukusebenza kombane.

2. Khetha izixhobo ezifanelekileyo zokomba kunye neteknoloji:

Ukuqinisekisa ukuchaneka kokomba, tyala imali kwizixhobo ezikumgangatho ophezulu zokomba ezivumela ulawulo oluchanekileyo lwesantya sokomba, ubunzulu kunye nolungelelwaniso. Oomatshini bokwemba ngokuzenzekelayo abaneempawu eziphambili ezifana nokugrumba okuncediswa nge-laser kunye nokuchaneka kokulawulwa yikhompyuter kucetyiswa kakhulu. Ukongeza, qwalasela i-laser-drilled microvias kwiibhodi zamanqanaba amaninzi njengoko zibonelela ngokuchaneka okuphezulu kunye nokuthembeka.

3. Uyilo olugqwesileyo lokupakisha:

Uyilo oluchanekileyo lokupakisha ludlala indima ebalulekileyo ekufezekiseni ukuchaneka kokomba kunye nomgangatho wodonga lomngxuma. Nceda uqwalasele la macebiso alandelayo:
- Nciphisa inani leeleya zemiqondiso ukunciphisa ubunzima bokomba.
- Gcina iyunifomu yobungqingqwa ukukhusela imingxuma yokugrumba ekutyekeni.
- Sebenzisa ukuhanjiswa kobhedu olulungeleleneyo ukuphepha ukugoba kunye nokujika ngexesha lokomba.
- Beka imiqondiso yesantya esiphezulu kunye namalungu anovakalelo kude nendawo egrunjiweyo ukunciphisa umngcipheko wokuphazamiseka kombane.

4. Inkqubo yokwenziwa kwePCB echanekileyo:

I-Capel ineminyaka eyi-15 yamava kwaye ilandela iinkqubo ezingqongqo zokuvelisa ukuqinisekisa ukuchaneka kokomba kunye neendonga zomngxuma ophezulu kwi-4-layer PCB stack-ups. Ngamaziko akumgangatho ophezulu kunye nabasebenzi abanezakhono, basebenzisa ubuchwepheshe obuphezulu obufana ne-Laser Direct Imaging (LDI) kunye noHlolo oluSebenzayo lwe-Optical Inspection (AOI) ukwenzela ukulungelelaniswa okuchanekileyo kunye nokuhlolwa komgangatho ngexesha lenkqubo yokuvelisa. Obu buchule buqinisekisa iiPCBs ezithembekileyo, ezomeleleyo kubathengi.

5. Amanyathelo okulawula umgangatho abanzi:

Ukuzinikela kweCapel kulawulo lomgangatho kubonakaliswa kwiinkqubo zayo zokuhlola ngokungqongqo. Basebenzisa iindlela zokuvavanya eziphambili, kubandakanya uvavanyo lombane, uvavanyo lokuthembeka kunye novavanyo lokuguga kwe-thermal. Ngokubeka iliso ngexesha langempela kunye nokuthotyelwa kwemigangatho yomgangatho wamazwe ngamazwe, iCapel iqinisekisa ukuba yonke i-PCB abayenzayo idibana okanye idlula ukulindela kwabathengi.

6. Iprotoyipu yePCB yaseCapel kunye neenkonzo zendibano:

Njengomboneleli wezisombululo ze-PCB eziye ziphele, iCapel ayigxininisi nje ekuveliseni i-PCB ene-4-layer stack-ups, kodwa ikwabonelela ngeprototyping ye-PCB ekhawulezayo kunye neenkonzo ezisebenzayo zendibano ye-SMT PCB. Le ndlela elungelelanisiweyo iphelisa imfuno yababoneleli abaninzi kwaye iqinisekisa ukuhlanganiswa okungenamthungo kuzo zonke izigaba zemveliso yePCB, ngaloo ndlela igcina ixesha kunye nokunciphisa iindleko kubathengi bayo abaxabisekileyo.

Ukuququmbela:

Xa kuziwa ekufezekiseni ukuchaneka kwe-drilling kunye nomgangatho wodonga lomngxuma kwi-stackup ye-PCB ye-4-layer, ukusebenza kunye nomenzi we-PCB onamava kunye nothembekileyo njengoCapel kubalulekile.I-Capel ivelele kwishishini ngokugxininisa kulawulo lomgangatho, iteknoloji ephuculweyo kunye nezisombululo ezibanzi zePCB ze-turnkey. Ngokubeka phambili ukuchaneka kokomba kunye nomgangatho wodonga lomngxuma, unokuqinisekisa ukusebenza okuphezulu kunye nokuphila ixesha elide kwezixhobo zakho zombane.
