Zininzi iindawo ngaphakathiUyilo lwe-PCBapho ukutya okukhuselekileyo kufuneka kuthathelwe ingqalelo. Apha, ihlelwe okwethutyana yangamacandelo amabini: Inye i-Spaceral Spaceral Spires, enye ingeyona i-Spaceral yoKhuseleko eNgcwele yoMbane.
Ukhuseleko olunxulumene nombane
1.Ukuchazwa phakathi kweengcingo
Ukuya kuthi ga ngokusekwa komthamo we-piestreamAbavelisi bePCBIxhalabile, ubuncinci besithuba phakathi kweengcingo asiyi kuba ngaphantsi kwe-4mIl. Owona mgama ucingo lomgama umgama umgama ukusuka kwintambo kwi-wire kunye nentambo kwi-pad. Ukusuka kwimbono yemveliso, enkulu engcono ukuba kunokwenzeka, kwaye i-10mil yinto eqhelekileyo.
2.Parture aperture kunye nobubanzi bepad
Ngokuphathelelene nomthamo we-PHB of Pightstream, i-aperture yepali akufuneki ibe ngaphantsi kwe-0.2mm ukuba igqitywe ngoomatshini, kunye ne-4ml ukuba i-laser ikhutshiwe. Ukunyamezelana kwe-adrerture kwahlukile kancinci ngokweplate, ngokubanzi kunokulawulwa ngaphakathi kwe-0.0mmm, obu bubanzi bepali akufuneki bube ngaphantsi kwe-0.2mm.
3.Ukuveliswa phakathi kwepad
Ukuya kuthi ga ngoku umsebenzi wokuqhubekisa kwabavelisi bePCB ePrighttyream echaphazelekayo, isithuba phakathi kweepads aziyi kuba ngaphantsi kwe-0.2mm.
4. Umgama phakathi kobhedu kunye nomphetho weplate
Isithuba esiphakathi kwesikhumba sobhedu kunye nomphetho weIbhodi yePCBakufuneki ibe ngaphantsi kwe-0.3mmm. Kwiphepha lokuhambisa le-SIBE-CoAME
Ukuba indawo enkulu yobhedu ibekwe, kuhlala kukho umgama ophakathi kweplate kunye nomphetho, obekwe rhoqo kwi-20mil. Kuyilo ye-PCB kunye nemveliso yemveliso, phantsi kweemeko eziqhelekileyo, ngenxa yokuqwalaselwa koomatshini weBhodi yeSiphalo egqityiweyo, okanye ukunqanda isiphatho seBhodi, kunokubangela ulusu lweBhodi yeBhodi.
Olu luhlu lobhedu lunokusingathwa ngeendlela ezahlukeneyo, njengokuzoba ungqimba lwe-keepout ecaleni kweplate, emva koko umisele umgama phakathi kobhedu kunye ne-keepout. Indlela elula yaziswa apha, oko kukuthi, imigama eyahlukeneyo yokhuseleko icwangciselwe ukubeka kobhedu. Umzekelo, umgama wokhuseleko kwiBhodi iphela usekwe kwi-10mIl, kwaye ubhedu lubekwe kwi-20mil, enokufumana isiphumo sokuncitshiswa kweBhodi kwaye ishenxise ubhedu lweBhodi.
I-Spring engekhoyo yoKhuseleko
I-1. Ububanzi bomlo, ukuphakama kunye nokuvalwa
Akukho lutshintsho lunokwenziwa ekuqhubelweni kwefilimu yokubhaliweyo, kodwa ububanzi bomgca wabalinganiswa ongezantsi kwe-0.22mm (8.66mm) kwi-D-khowudi ye-D-CORMMS, i-0.22mm (8.66mil).
Ububanzi bomntu wonke yi-W = 1.0mmm, ukuphakama komlinganiswa uphela yi-H = 1.2mm, kunye ne-Spactor, kunye ne-Spiac, kunye ne-Spacking phakathi koonobumba yi-D = 0.2mm. Xa isicatshulwa singaphantsi komgangatho olapha ngasentla, ukuprintwa kuqhawulwe.

3.Distance ukusuka kwi-screen yokuprinta kwi-pad
Ukuprintwa kwesikrini akuvunyelwanga ukugubungela i-pad. Kungenxa yokuba ukuba iprinta yesikrini igubungele i-Portermer Pary, iprinta yesikrini ayiyi kuba kwi-tin xa i-tin iqhubeka, eya kuchaphazela indawo yokuphakama kwecandelo. Umzi-mveliso webhodi jikelele ufuna ukuba isithuba se-8MIl sigcinelwe. Ukuba ibhodi ye-PCB inqunyelwe kwindawo, isithuba se-4MIL asimkelekile. Ukuba ukuprintwa kwesikrini kugqithiselwe ngengozi kwipali ngexesha loyilo, umzi-mveliso waseplate uzakuphelisa ngokuzenzekelayo ukuprintwa kwe-pad ngexesha lokuvelisa ukuqinisekisa i-TIN.
Ewe kunjalo, yindlela yecala lecala ngexesha loyilo. Ngamanye amaxesha iprinti yescript igcinwe ngabom kwi-pad, kuba xa iipads ezimbini zisondelelene, iprinti eprintiweyo ngaphakathi inokuthintela ngokufanelekileyo ukuqhagamshelwa kweThuthi kwiTolder, lelinye icala.
4.Ukuphakama kwe-4MXICT
Xa ufaka izinto kwiI-PCB, kuyimfuneko ukuqwalasela ukuba isikhokelo esithe tyaba kwaye ukuphakama kwendawo kuya kungqubana nezinye izinto zoomatshini. Ke ngoko, kuyilo, kufuneka siqwalasele ngokupheleleyo ukuhambelana phakathi kwezinto, phakathi kwemveliso ye-PCB kunye neqokobhe lemveliso, kunye nokugcinwa kwendawo, kunye nokugcina indawo ekhuselekileyo yento ekuqinisekiseni ukuba akukho kungqubana kwindawo.
