Gufata imyenge ya SMT stencil kenshi bigatuma umusaruro ugabanuka cyane? Guhitamo isuku nziza ya stencil ni ingenzi cyane.

Mu gikorwa cyo guteranya PCB ku buso, impapuro zo guhanagura stencil ni ibikoresho bisukuye bikoreshwa cyane mu icapiro, nyamara ni n'ikintu kigira ingaruka ku musaruro gikunze kwirengagizwa. Impapuro zo guhanagura stencil zifite urwego rumwe ziboneka ku isoko ntizifite imbaraga zihagije zo guhuza fibre; iyo zishyizwe mu gikoresho cyo gusukura cya IPA kugira ngo zihanagure ibisigazwa bya solder paste munsi ya stencil, zikunze kwangiza uduce duto twa fibre. Izi fibres nziza cyane zishobora kwinjira mu mwobo wa stencil nziza, bigatuma umwobo uziba nyuma yo gukora igihe kirekire. Ibi bitera inenge nko kudakoresha neza solder, bridging na solder balls. Guhagarara kenshi mu gukora stencil bigabanya umusaruro rusange w'umuyoboro kandi byongera ikiguzi cy'ikigo ku bikoresho n'umurimo.
Mu gukemura ikibazo cy’inganda zikoresha stencil mu gushonga no kuziba kwa fibre, impapuro zacu zihariye zo guhanagura stencil zifite imiterere myiza y’ubutaka, zitanga inyungu nyinshi zifatika:

Imiterere y'uruvange rw'ibice bibiri, ikozwe nk'igice kimwe nta kole irenze urugero;

Ifite ivumbi rike kandi ridafite irangi, hamwe n'ingufu nke zitakaza mu gihe cyo guhanagura;

Inyubako ifite imyenge itanga ubushobozi bwo kwinjiza amazi n'uburyo bwo gufata ibintu byanduye, ikwinjiza neza ibisigazwa by'amazi n'amazi;

Iboneka mu bugari butandukanye, ifite ingano z'ibanze zishobora guhindurwa kugira ngo zijyane n'imashini zikoresha ikoranabuhanga rya mudasobwa zisanzwe nka DEK na MPM;

Ikorana neza cyane n'imiti; ntiyonona cyangwa ngo ikuremo imyanda ndetse no mu gihe kirekire ihuye na IPA n'ibindi bikoresho bitandukanye byo gusukura.

Imiterere mike y'ivumbi n'ubudahangarwa ni byo biranga ingenzi bitandukanya impapuro zo guhanagura za SMT nziza n'ibicuruzwa bisanzwe. Iki gicuruzwa gikoresha polyester ya filament hamwe n'uburyo bwo gufungana hakoreshejwe pulp y'ibiti bya virgin, nta gukoresha kole za shimi, bituma insinga ziguma zifatanye neza haba mu gihe cyumye n'igihe cy'ubukonje. Mu guhanagura stencil, nta budodo cyangwa imyanda ikorwa; ibisigazwa by'amabati meza n'ifu isohoka bifungirwa mu mwenge w'imbere w'impapuro, bikarinda imyanda kuguma mu mwenge wa stencil cyangwa gukwirakwira mu cyumba cy'isuku. Bikwiriye imiyoboro ya SMT yo mu cyiciro cya 1,000 na 10,000, bigabanya inenge zo gushyiramo stencil ziterwa n'imyanda y'impapuro, bigabanya inshuro zo kudakora isuku, kandi bigatuza umusaruro.

Iyi mpapuro yo guhanagura idafite ivumbi ikoreshwa cyane mu gukora ibikoresho by'ikoranabuhanga, imiyoboro mishya y'amashanyarazi ndetse no gushyiramo chip nziza. Ikwiriye guhanagura ikoresheje intoki mu buryo bwa semi-automatic ndetse no guhanagura ikoresheje intoki mu buryo buhoraho, ku mashini zicapa zikoresha ikoranabuhanga. Ibisubizo byihariye mu bunini butandukanye bishobora guhindurwa kugira ngo bihuze n'ibikoresho bisanzwe by'ikigo, bikuraho gusimbuza imashini, ibikoresho cyangwa ibikoresho; ibikoresho birwanya solvent ntibicika intege, bitanga imbaraga zo gusukura neza kuri buri guhanagura kandi bigabanya inshuro zo gusimbuza ibikoresho mu gihe kirekire.

Ku nganda zikora SMT, impapuro zo guhanagura za stencil zisa n’izidatangaje zigira ingaruka zitaziguye ku musaruro w’aho zishyirwa. Guhitamo impapuro zo guhanagura za stencil zifite ivumbi rike kandi zishobora gufata cyane bishobora kugabanya ikibazo cyo kuziba kw’imyobo ya stencil aho ituruka, bityo bigafasha mu gucunga isuku mu buryo busanzwe mu iduka.
