Amaphutha kanye Nezixazululo Ezijwayelekile Zenqubo Yokubhola ye-PCB

Enqubweni yokukhiqiza i-PCB , ukubhoboza kuyisinyathelo esibalulekile esidinga ukunemba nokunemba. Kodwa-ke, kungavela izinkinga eziningana ngesikhathi sokubhoboza, okuholela emaphutheni ku-PCB yokugcina. Lesi sihloko sixoxa ngamaphutha avamile enqubo yokubhoboza i-PCB, izimbangela zawo, kanye nezixazululo zokuqinisekisa inqubo yokubhoboza ebushelelezi nephumelelayo.

1. I-Drill Bit Breakage

Izimbangela:

• Ukuchezuka okweqile kwe-spindle.
• Ukusebenza okungalungile ngesikhathi sokumba.
• Ukukhetha okungafanelekile kwebhithi yokubhoboza.
• Isivinini sokubhoboza esinganele, izinga lokuphakelayo eleqile.
• Inani eleqile lamabhodi astakiwe.
• Ukuba khona kwemfucumfucu ngaphansi kwebhodi noma phakathi kwamabhodi.

Izixazululo:

1. Yazisa uchwepheshe ukuthi ahlole futhi alungise i-spindle noma esikhundleni saso afake esisha.
2. Hlola i-geometry, ukuguga, futhi usebenzise izinsimbi zokubhoboza ezifanele ezinobude obufanelekile be-chip flute.
3. Khetha izinga lokuphakelayo elilungile futhi unciphise isivinini sokumba.
4. Yehlisa inani lamabhodi astakiwe libe sezingeni elifanele.
5. Hlanza ingaphezulu lebhodi futhi ususe noma iyiphi imfucumfucu ngaphansi noma phakathi kwamabhodi.
6. Lungisa ukujula kokuphotha ngesikhathi sokumba ukuze uqinisekise ukususwa kwe-chip okufanele.
7. Lawula inani lemisebenzi yokulola ngokuya ngemanuwali yokusebenza noma amapharamitha.
8. Khetha amabhodi ekhava nama-spacer anobulukhuni obufanele kanye nokucaba.
9. Hlola isimo sokulungisa itheyiphu nobubanzi, bese ubuyisela ishidi le-aluminium yekhava yebhodi uma kunesidingo.
10. Yehlisa izinga lokuphakelayo ngendlela efanele.
11. Naka ukugcwalisa imbobo okulungile ngesikhathi sokusebenza.
12. Faka esikhundleni izingcezu zokubhoboza indawo efanayo.

2. Ukulimala Kwemigodi

Izimbangela:

• Ukukhipha i-drill bit ngemva kokuphuka.
• Ukubhoboza ngaphandle kweshidi le-aluminium noma ipuleti elingezansi elihlehlayo.
• Amapharamitha angalungile.
• I-Drill bit elongation.
• Ubude obanele obusebenzayo be-drill bit yobukhulu bebhodi.
• Ukubhoboza imbobo mathupha.
• Izinto zebhodi ezikhethekile ezibangela ama-burrs.

Izixazululo:

1. Khomba futhi ubhekane nembangela yokuphuka kwe-drill njengokusho kwephuzu langaphambilini.
2. Amashidi e-aluminium namapuleti aphansi asebenza ukuvikela iringi yembobo. Zisebenzise ngaso sonke isikhathi, futhi uhlole indawo ezikuyo nendlela ezikuyo ngaphambi kokugibela.
3. Ngaphambi kokubhoboza, hlola ukuthi ukujula kwembobo kuyahambisana yini nemingcele, futhi uqinisekise ukuthi i-drill bit ngayinye isethwe ngendlela efanele.
4. Hlola ubude bebhithi yokubhoboza ngokubuka ngaphambi kokugibela futhi uqinisekise ukuthi ihlangabezana nezidingo zokulinganisa isitaki sebhodi lokukhiqiza.
5. Ukugaya ngesandla akuvunyelwe, njengoba kungahlangabezani nezidingo zokunemba, isivinini, njll.
6. Khetha amapharamitha ngokufanele ngezinto zebhodi ezikhethekile futhi uqinisekise ukuthi isivinini sokubhoboza sifanelekile.

3. Ukungahambi kahle Kwembobo

Izimbangela:

• Ukuchezuka kwebhithi ye-drill ngesikhathi sokumba.
• Ukukhetha okungalungile kwezinto zebhodi lekhava, ubulukhuni, noma ukucaba.
• Ukunwetshwa nokufinyezwa kwe-substrate kubangela ukuchezuka kwembobo.
• Ukusetshenziswa okungalungile kwamathuluzi okufaka nokubeka indawo.
• Ukusetha okungalungile konyawo lokucindezela ngesikhathi sokubhoboza, ukushaya iphinikhodi yokumisa, okwenza ibhodi lokukhiqiza lihambe.

Izixazululo:

• A, Hlola ukuthi i-spindle iphambukisiwe yini. B, Nciphisa inani lamabhodi astakiwe, ngokuvamile libe izikhathi eziyisi-6 kunobubanzi bokubhoboza amabhodi anezinhlangothi ezimbili kanye nezikhathi ezingu-2-3 kumabhodi anezinhlaka eziningi. C, Khulisa isivinini sokubhoboza noma unciphise izinga lokuphakelayo. D, Hlola ukuthi i-drill bit iyahlangabezana yini nezidingo zenqubo, futhi uyigaye uma kunesidingo. E, Hlola ukujula phakathi kwethiphu yebhithi yokubhoboza nesibambo sebhithi yokubhoboza. F, Hlola isimo sokulungisa phakathi kwe-drill bit kanye ne-spring chuck, futhi ulungise noma ufake esikhundleni se-spring chuck uma kunesidingo. G, Hlola futhi ulungise ukuzinza nokuthambile kwebhentshi lokusebenza.
• Khetha ibhodi lekhava elinobukhulu obungu-0.50mm noma ulishintshe ufake ibhodi lekhava eliyinhlanganisela (izendlalelo ezimbili ze-aluminium foil enogqinsi luka-0.06mm phezulu naphansi, kanye ne-fiber core phakathi, enogqinsi oluphelele 0.35mm).
• Ngokwezici zebhodi, yenza ukwelashwa kokubhaka ipuleti ngaphambi noma ngemuva kokumba (ngokuvamile ku-145C + 5C, ukubhaka amahora angu-4).
• Hlola noma hlola ukunemba kosayizi wembobo yethuluzi kanye nokuma kwephinikhodi yokumisa.
• Hlola futhi usethe kabusha ukuphakama konyawo lokucindezela. Ukuphakama konyawo lwengcindezi evamile kungu-0.80mm ukusuka endaweni yebhodi.
• Khetha isivinini sokuprakthiza esifanele. Hlanza noma shintsha i-spring chuck.
• Ibhodi alifakiwe izikhonkwane zokumisa, izikhonkwane zebhodi lokulawula ziphansi kakhulu noma azikhululekile, futhi izikhonkwane zidinga ukumiswa kabusha futhi kushintshwe.
• Khetha isilinganiso sokuphakelayo esifanelekile noma i-drill bit enamandla angcono okugoba.
• Buyisela ishidi le-aluminium lekhava lebhodi libe nendawo ebushelelezi nengenamklebhu.
• Sebenzisa ukugcwalisa imbobo ngendlela efanele ngesikhathi sokusebenza.
• Rekhoda futhi uqinisekise umsuka.
• Namathisela iphepha lokunamathisela nge-engeli engu-90-degree onqenqemeni lwebhodi.
• Impendulo futhi wazise uchwepheshe ukuthi alungise futhi alungise umshini wokumba.
• Hlola futhi uqinisekise, futhi wazise umnyango wobunjiniyela ukuze wenze izinguquko.

Isiphetho

Sekukonke, amaphutha enqubo yokubhoboza i-PCB angaholela emaphutheni amakhulu futhi athinte ikhwalithi iyonke ye-PCB. Ngokuqonda izimbangela zala maphutha nokusebenzisa izixazululo ezifanele, abakhiqizi bangaqinisekisa inqubo yokubhoboza ebushelelezi nephumelelayo, ekugcineni okuholela kuma-PCB asezingeni eliphezulu. Ukugcinwa njalo kwemishini yokubhoboza, ukukhethwa kahle kwezingcezu zokubhoboza, kanye nokunamathela kumingcele yokubhoboza kuyizinto ezibalulekile ekuvimbeleni la maphutha nokuqinisekisa ukuthembeka komkhiqizo wokugcina we-PCB.

Onjiniyela bavame ukuqinisekisa lesi sihloko kanye nokwakhiwa kwe-PCB ye-laminate ene-low-loss ekhethekile kanye ne -AlN kanye ne-alumina PCB lapho belungiselela i-PCB noma i-PCBA ethembekile.
