Senza Ntoni Umshicileli Westencil?

I. Iintlobo zeprinta zestencil

1. Isishicileli seStencil seManuwali

Umshicileli wesandla yeyona ndlela ilula nefikelelekayo yoshicilelo.Ukubekwa kwePCB kunye nokususwa kwenziwa ngesandla, i-squeegee ingasetyenziswa ngesandla okanye iqhotyoshelwe kumatshini, kwaye isenzo sokushicilela senziwe ngesandla.PCB kunye ipleyiti yentsimbi parallelism ulungelelwaniso okanye emphethweni webhodi ukuqinisekisa isikhundla zixhomekeke izakhono umqhubi, ngoko PCB eprintiweyo nganye, parameters yoshicilelo kuya kufuneka ukuba luhlengahlengiswe kwaye utshintshwe.

2. Umatshini woshicilelo ozenzekelayo

Oomatshini bokushicilela beSemi-automatic okwangoku sesona sixhobo sokushicilela sisetyenziswa kakhulu, eneneni bayafana kakhulu noomatshini bokushicilela bezandla, ukubekwa kunye nokususwa kweePCB kusaxhomekeke ekusebenzeni ngesandla, umahluko ophambili ngomatshini wesandla kuphuhliso lwentloko yoshicilelo, inokulawula ngcono isantya soshicilelo, uxinzelelo lwe-squeegee, i-angle ye-squeegee, umgama wokushicilela kunye ne-pitch non-contact, imingxunya yesixhobo okanye imiphetho ye-PCB isasetyenziselwa ukubeka, ngelixa inkqubo yepleyiti yensimbi yokunceda abasebenzi Ukugqitywa kakuhle kwe-PCB kunye nohlengahlengiso lweplate yensimbi parallelism. .

3. Umatshini wokushicilela ozenzekelayo ngokupheleleyo

I-solder paste iprintwa kwiipads zamacandelo ebhodini lesiseko, kodwa namhlanje ubukhulu bezinto ezifakwe phezulu ziba zincinci kwaye zincinci, ngoko ke ukuyila kwebhodi yesiseko sesekethe ngokuhambelanayo kuncinci kwaye kuncinci.Ngoko ke, ukuchaneka kunye nokusebenza kakuhle koshicilelo lwe-solder paste kufuneka kuphuculwe kakhulu.Kule mihla, uninzi lwabavelisi bemveliso ye-elektroniki basebenzisa oomatshini bokuprinta be-solder oluzenzekelayo okanye oluzenzekelayo ngokupheleleyo ukuvelisa iimveliso ze-SMT, kunye nokubekwa kwe-PCB kwenziwa ngebhanti lokuhambisa elinomphetho, kunye neeparitha zenkqubo ezifana nesantya, uxinzelelo lwe-squeegee, ubude bokushicilela, kunye non-uqhagamshelwe pitch yonke programmable.

Ukubekwa kwe-PCB kwenziwa ngokusebenzisa imingxunya yokubeka okanye imiphetho yebhodi, kwaye ezinye izixhobo zinokusebenzisa iinkqubo zombono ukuze zilungelelanise i-PCB kunye nepleyiti yentsimbi ehambelanayo enye kwenye, ephelisa iimpazamo ezibangelwa kukubekwa komphetho xa usebenzisa iinkqubo zombono ezinjalo, kwaye yenza kube lula ukumisa, ngoqinisekiso lokumiswa kwezandla endaweni yalo ziinkqubo zombono.Iiprinta ezintsha ze-solder paste zixhotyiswe ngeelensi zevidiyo ukujonga imeko yoshicilelo kunye nokwenza izilungiso nangaliphi na ixesha.
 

II.Ukugcinwa kweprinta yestencil

Susa i-squeegee, sebenzisa iphepha elikhethekileyo lokusula elifakwe kwi-ethanol ye-anhydrous, sula i-squeegee ecocekileyo, kwaye emva koko ifakwe kwintloko yokushicilela okanye ifunyenwe kwikhabhinethi yesixhobo.
Coca i-stencil, kukho iindlela ezimbini.

Indlela yoku-1: Ukucoca umatshini wokuhlamba.Ukuhlamba izixhobo nge template, umphumo wokucoca ungcono kakhulu.

Indlela yesi-2:Ukucoca ngesandla.

Sebenzisa iphepha elikhethekileyo lokusula ukuze usebenzise i-ethanol ye-anhydrous, i-solder paste iya kuhlanjululwa, ukuba ukuvuza komngxuma ukuvala, kufumaneka ngebrashi yamazinyo ethambileyo, musa ukuhlatywa ngenaliti enzima.

Sebenzisa umpu womoya ocinezelweyo ukuvuthela intsalela kumngxuma wokuvuza wetemplate ucoceke.

Beka itemplate kumatshini wokulayisha uncamathisele, kungenjalo yifumane kwikhabhinethi yesixhobo.
