I-1. Umphezulu we-PCB: I-OSP, i-Hasl-Fide-Free-I-TIn, i-Inig, i-Enig, iSpeyinti yeBhodi, igolide yegolide, i-Enepig ...
I-OSP: Ixabiso eliphantsi, impahla entle, iimeko zokugcina ezinzima, ixesha elifutshane, itekhnoloji yendalo, i-welding elungileyo, egudileyo ...
I-Hasl: Ngokwesiqhelo ziisampulu ze-HDI ze-HDI (4 - 46), isetyenziswe ngonxibelelwano olukhulu, iikhompyuter, izixhobo zonyango kunye ne-aerospace amashishini kunye neeyunithi zophando.
Umnwe wegolide: Lunxibelelwano phakathi kwememori slot kunye nememori chip, zonke iimpawu zithunyelwa ngumnwe wegolide.
Umnwe wegolide uthintelo lwamanani abafowunelwa obukhulu begolide, obizwa ngokuba yi "umnwe wegolide" ngenxa yomphezulu wegolide-eprinta kunye nelungiselelo labo. Umnwe wegolide usebenzisa inkqubo ekhethekileyo kwiCopper yeCopara ejongene negolide, exhaphake kakhulu kwi-oxidation kwaye iphumelele kakhulu. Kodwa ixabiso legolide libiza kakhulu, i-tin ye-tin yangoku isetyenziselwa ukutshintsha inkumbulo ngakumbi. Ukususela kwinkulungwane ephelileyo 90 s, izinto ze-tin zaqala ukusasazeka, ibhodi yamalungu, inkumbulo, iiNgqondo zeVidiyo "ziphantse zasebenza kwi-tin ye-tin, ke ixabiso lingabizi kangako.
2. Kutheni usebenzisa iBhodi yeGolide?
Ukudityaniswa kwe-IC ephezulu nangaphezulu, iinyawo ezingaphezulu nangaphezulu. Ngelixa inkqubo yokutshiza ethe nkqo inzima ukuvuthela i-pid ye-pid ye-pid, ezisa ubunzima kwi-SMT. Ukongeza, ubomi beshelfu ye-tin yokutshiza bufutshane kakhulu. Nangona kunjalo, ipleyiti yegolide isombulula ezi ngxaki:
1.) KwiTekhnoloji yeNtaba yeNtaba yeNtaba yeNtaba ye-0603 kunye ne-0402 kunye ne-0402 intaba yetafile ye-Welding ihambelana ngqo nomgangatho we-welding yenkqubo ye-themerting ihambelana noxinzelelo lwe-thertan kwi-Ultra-Cheature.
2.) Kwisigaba sokukhula, impembelelo yezinto ezinjengokuthengwa kwempahla ihlala inganguye iBhodi ngokukhawuleza, kodwa kudla ngokulinda iiveki ezimbalwa okanye iinyanga zeBhodi yegolide ixeshana kangangexesha elide, ukuze wonke umntu azimisele ukwamkela. Ngaphandle koko, i-PCB eplate yegolide kwiidigri zendleko zenqanaba lesampulu xa kuthelekiswa neepleyiti zepewter
Kodwa nge-wiring engaphezulu nangakumbi yobubanzi, ububanzi obunamacandelo, indawo ifikelele kwi-3-4mlil
Ke ngoko, izisa ingxaki yesekethe emfutshane yegolide yegolide: kunye nokwandisa irenti yesayizi, ifuthe lokudluliselwa kwesiginali kwi-coactions ezininzi ngenxa yefuthe lolusu ngenxa yolusu ngakumbi
.
3. Kutheni usebenzisa iPCB yokuntywila?
Kukho ezinye iimpawu zokuntywila kwi-PCB ye-PCB njengezantsi:
1.) Isakhiwo sekristale eyenziwe ngegolide kunye nokubethwa kwegolide kwahlukile, umbala wegolide unokulunga ngakumbi kunesitayile segolide kwaye umthengi wanelisekile. Emva koko uxinzelelo lweplate yegolide engaphantsi kulula ukuyilawula, elungele ngakumbi ukulungiswa kweemveliso. Kwangelo xesha linye ngenxa yokuba igolide ithambile kunegolide, ke iplate yegolide ayinxibi ngumnwe wegolide enganyangekiyo.
2.) Igolide yokuntywila kulula ukuyila ilukhuni kunokuba i-Proting yegolide, kwaye ayizukubangela izikhalazo ezingezizo kunye nezikhalazo zabathengi.
3.) Igolide ye-Nickel ifumaneka kuphela kwi-pid ye-welb ye-enig PCB, ukuhanjiswa kwesiginali kwimpembelelo yolusu kusekethelela umqondiso, ongayi kuphatha umqondiso wegolide. Umthengi kwisekethe kwisekethe udityaniswe ngokuqinileyo kunye ne-copper.
4.) Ulwakhiwo lwekristali yeGolide yokuntywila i-Debser kunombhalo wegolide, kunzima ukuvelisa i-oxidation
5.) Akuyi kubakho mpembelelo kwi-spacking xa imbuyekezo yenziwe
6.) Iflethi kunye nenkonzo yenkonzo yegolide ilungile njengaleyo yeplate yegolide.
I-4. Ukuntywila ngegolide i-vs
Zimbini iintlobo zetekhnoloji yegolide yegolide: Inye i-propital yegolide, enye igolide yokuntywila.
Inkqubo yendlela yokufaka igolide, impembelelo ye-tin incitshisiwe kakhulu, kwaye umphumo wegolide ungcono; Ngaphandle kokuba umenzi ufuna ukubopha, okanye ngoku abavelisi baya kuyikhetha inkqubo yegolide!
Ngokubanzi, ukuphathwa komhlaba wePCB kunokwahlulwahlulwahlulwahlulwa kwezi ntlobo zilandelayo: Ukubethwa kwegolide (i-elektroplay, igolide ye-CREAT, i-CAMS-3 ye-CROS, izixhobo zephepha, i-rosin ye-DR4 okanye ePhezulu iCoping Proper; Kwi-tin ihlwempu (ngokutya i-tin ihlwempu) oku ukuba ukususwa kwabavelisi bencamathisi kunye nezizathu zokulungisa izinto.
Kukho izizathu ezithile zengxaki ye-PCB:
1.Ukuprinta i-PCB, nokuba kukho umphezulu wefilimu kwi-pan, inokubhlokho i-tin; Oku kunokuqinisekiswa yi-PRORTARY PROAT
2.Umkuthile isikhundla esivela kwipaneli sinokuhlangabezana neemfuno zoyilo, oko kukuthi, nokuba i-palang ye-welding ingayilwa ukuqinisekisa inkxaso yamalungu.
3.Upas welding ayingcoliswanga, nto leyo inokulinganiswa ngungcoliseko lwe-ion.
Malunga nomphezulu:
Ukubethwa kwegolide, kunokwenza ixesha lokugcina i-PCB ixesha elide, kwaye ngeqondo lobushushu bangaphandle kunye nemeko yokutshintsha kwendalo kunye ne-subty incinci (xa kuthelekiswa nonyango lomphezulu), ngokubanzi linokugcinwa malunga nonyaka; I-Hasl okanye i-Cound Shicil Shicil Ratel yesibini, i-OSP kwakhona, impatho yothintelo lomhlaba olandelayo ukuze ithathele ingqalelo iphantsi kweemeko eziqhelekileyo, ixabiso le-sublor linokufunwa kakhulu, imfuneko yokusetyenziswa kwe-Sulffur yephepha! Kwaye gcina kangangeenyanga ezintathu! Kwisiphumo se-TIN, igolide, i-osp, i-tin yokutshiza inyani, abavelisi ikakhulu kukuqwalasela ukusebenza kweendleko!
