Ukuthintela imingxunya yokubekwa kunye ne-welding ibandakanya uvavanyo lweenkqubo ezintsha zokwenza izinto kunye nokuhlalutya iziphumo. Ukubeka i-vointing kunye ne-welding idla ngokufumana izizathu ezichongiweyo, ezinje ngohlobo lomthengisi ichithwa okanye iqhume kancinci kwinkqubo yokuphucula. Abavelisi be-PCB banokusebenzisa inani lezicwangciso eziphambili zokuchonga nokulungisa oonobangela obuqhelekileyo kwezi voids.

1.Ukuhlala i-curve yeqondo lokushisa

Enye yeendlela zokuthintela i-welding cavies kukutshintsha indawo ebalulekileyo ye-curve. Ukunika amanqanaba ahlukeneyo ixesha anokonyuka okanye anciphise ukubakho kweemvakalelo zokwenza. Ukuqonda iimpawu ezifanelekileyo ze-curve zibalulekile ekuthinteleni ngempumelelo.

Okokuqala, jonga useto lwangoku lwexesha lokufudumala. Zama ukwandisa ubushushu obukhawulezileyo okanye ukwandisa ixesha lokuhamba kwe-curvel curve. Imingxunya yomthengisi inokubangela ngenxa yobushushu obungapheliyo kwindawo yokuhamba, ke sebenzisa ezi zicwangciso zokujongana nonobangela wengcambu.

Imimandla yobushushu yeHomogeneous ikwanjalo nemimandla eqhelekileyo ye-volpper. Amaxesha amafutshane aqaqambileyo anokungavumeli onke amacandelo kunye neendawo zeBhodi ukuze ufikelele kubushushu obuyimfuneko. Zama ukuvumela ixesha elongezelelweyo kule ndawo ye-curve.

2.Umbala kancinci

Kakhulu i-fluax inokukhulisa kwaye ihlala ikhokelela kwi-welding. Enye ingxaki nge-cavity edibeneyo: i-flux yokutshisa. Ukuba i-flux ayinalo ixesha elaneleyo lokufumana indawo, igesi egqithisileyo iya kubanjiswa kwaye kuya kwenziwa isinxibo.

Xa kusetyenziswa kakhulu i-bibb, ixesha elifunekayo lokuba i-flux ihlawulwe ngokupheleleyo. Ngaphandle kokuba wongeza ixesha elongezelelekileyo lokudinisa, i-flux eyongezelelweyo iya kukhokelela kwi-VIDS ye-WEDIDS.

Ngelixa ukongeza ixesha lokudinga okungaphezulu kunokusombulula le ngxaki, kuyasebenza ngakumbi ukunamathela kwinani le-flux efunekayo. Oku kugcina amandla kunye nezixhobo kwaye kwenza ukuba umboniso wokudibana.

3.Umntu obukhali kuphela

Isizathu esiqhelekileyo sokubeka imingxunya ihlwempuzekile ngokugqobhoza umngxunya. I-bits ezixineneyo okanye ukuchaneka okungalunganga kunokunyusa ukubakho kwendlela yokufota kwenkunkuma ngexesha lokuqhuba. Xa ezi ziqwenga zinamathela kwi-PCB, zenza iindawo ezingenanto ezingenakubhalwa ngobhedu. Oku kulatshwa, umgangatho kunye nokuthembeka.

Abavelisi banokusombulula le ngxaki ngokusebenzisa kuphela i-bits ebukhali nebukhali. Seka ishedyuli engaguqukiyo yokuqina okanye yokutshintsha i-bits ye-dill, enje ngekota. Olu londolozo oluhlala lusebenza luya kuqinisekisa ngokulinganayo ngomgangatho wokuntywila kwaye unciphise ukubakho kwenkunkuma.

4.Ukuyini itemplate eyahlukeneyo

Uyilo lwetemplate esetyenziswa kwinkqubo yemvumi inokunceda okanye kuthintelwe ukuthintela i-voids. Ngelishwa, akukho sisombululo sihambelana nayo sonke isisombululo kwi-template yoyilo. Abanye beyilo lomsebenzi ongcono kwiThuthi yoThengiso eyahlukeneyo, iFlex, okanye iiPCB iintlobo. Kungathatha uvavanyo kunye nempazamo ukufumana ukhetho lohlobo oluthile lwebhodi.

Ukufumana ngempumelelo uyilo olufanelekileyo lwetemplate kufuna inkqubo yovavanyo elungileyo. Abavelisi kufuneka bafumane indlela yokulinganisa nokuhlalutya isiphumo sokuyilwa kwe-voids.

Indlela ethembekileyo yokwenza le nto kukudala i-batch ye-PCBS ngeyilo ethile yetemplate kwaye emva koko uhlole kakuhle. Iitemplate ezahlukeneyo zisetyenziselwa ukwenza oku. Uvavanyo kufuneka luveze ukuba zeziphi izinto ezenziweyo ezinemigangatho ye-mettor.

Isixhobo esiphambili kwinkqubo yokuhlola ngamatshini we-x-ray. I-X-ray yenye yeendlela zokufumana i-weldids i-welded kwaye iluncedo kakhulu xa ujongene neekkkmoya ezincinci, eziqingqiweyo. Ukuba umatshini ofanelekileyo we-X-ray uya kwenza inkqubo yokuhlola ibe lula kwaye isebenze ngakumbi.

Ireyithi yokuqhuba

Ukongeza kubukhali wencinci, isantya sokuqhuba siya kuba negalelo elikhulu kumgangatho wokubeka. Ukuba isantya se-bit siphezulu kakhulu, siya kunciphisa ukuchaneka kwaye kwandise amathuba okutsalwa kwenkunkuma. Izantya eziphezulu zokuqhuba zinokwandisa umngcipheko wokophula i-PCB, esongela ingqibelelo.

Ukuba imingxunya ixhaphakile emva kokuba ibukhali okanye iguqula intwana, zama ukunciphisa umgangatho wokuqhuba. Izantya ezicothayo zivumela ixesha elingakumbi lokwenza, ukucoceka kwimingxunya.

Gcina ukhumbula ukuba iindlela zemveliso zemveli azikokhetho namhlanje. Ukuba ukusebenza kakuhle kukuqwalaselwa ekuqhubeni amazinga aphezulu okuqhuba, ukuprinta i-3D kunokuba lukhetho olufanelekileyo. I-3D iprintiweyo iprintiwe isebenza kakuhle kunendlela yemveli, kodwa ichanekile okanye ichanekile. Ukukhetha iPCB eprintiweyo ye-3D isenokungafuni ukuqhuba ngemingxunya konke konke.

I-6.stick kwiThuthi esemgangathweni ephezulu

Kungokwemvelo ukukhangela iindlela zokugcina imali kwinkqubo yemveliso yePCB. Ngelishwa, ukuthenga ngexabiso eliphantsi okanye umgangatho weThuthi kunokuthintela ukubakho kokwenza i-voids.

Iipropathi zeekhemikhali ze-tricaients zeThuthisa abahlukeneyo ziyachaphazela ukusebenza kwazo kunye nendlela abanxibelelana ngayo ne-PCB ngexesha lenkqubo yeRecox. Umzekelo, ukusebenzisa i-Poter Paste yeThuthi engaqulathiyo inokuqulatha ngexesha lokupholisa.

Ukukhetha i-The Thenser esemgangathweni ephezulu kukufuna ukuba uqonde iimfuno ze-PCB kunye netemplate esetyenzisiweyo. Umthengisi weThuthisi

Kunokuba luncedo ekuvavanyeni i-upesi eyahlukeneyo ngaxeshanye njengokuvavanya iitemplate ezahlukeneyo. Ugxininiso lubekwe kusetyenziswa umthetho webhola oneminyaka emihlanu ukuze uhlengahlengise ubungakanani betemplate ye-template ukuze i-template ichithise itemplate. Umgaqo uxele ukuba abavelisi baya kusebenzisa ubuchule bee-apertures ezifunekayo ukuze kulunge iibhola ezintlanu. Lo mbono ubenza lula inkqubo yokwenza ucwangciso lwetemplate oxutyweyo ngokubhekisele kuvavanyo.

7.Redruce the the the the positing oxidation

I-Oxidation yeThuthisi iPakethi ihlala ivela xa kukho umoya omkhulu okanye umswakama kwindalo. I-oxidation ngokwayo inyusa amathuba okuqulunqa, kwaye ikwacebisa ukuba umoya ogqithisileyo okanye umswakama ngakumbi unyusa umngcipheko we-voids. Ukucombulula kunye nokunciphisa i-oxidation kunceda ukukhusela i-voids ekubenilisa kwaye kuphucule umgangatho we-PCB.

Jonga kuqala uhlobo loThemba loMthengisi osetyenzisiweyo. I-Playr Linca yokunyibilika emanzini ixhonyiselwa kakhulu kwi-oxidation. Ukongeza, i-rubex eyoneleyo inyusa umngcipheko we-oxidation. Ewe kunjalo, kakhulu kakhulu i-flux ikwayingxaki, ngoko abavelisi kufuneka bafumane ibhalansi. Nangona kunjalo, ukuba i-oxidation yenzeka, ukwandisa inani le-flux kungayisombulula ingxaki.

Abavelisi be-PCB banokuthatha amanyathelo amaninzi okuthintela ukubekwa kunye nemingxunya ye-welding kwiimveliso ze-elektroniki. I-VAIDS ichaphazela ukuthembeka, ukusebenza kunye nomgangatho. Ngethamsanqa, ukunciphisa amathuba okwenza i-voids ukwenziwa kulula njengokutshintsha komthengisi okanye ukusebenzisa uyilo olutsha lommiselo.

Usebenzisa indlela yokuvavanywa kovavanyo, nawuphi na umntu onokuthi afumane kwaye athethe nonobangela we-voids kwi-Rellux kunye neenkqubo zokubeka.
