Ni irihe tandukaniro riri hagati ya AOI na SPI20240904?

Gusobanukirwa igenzura rya SPI: Urufunguzo rw'inganda zikora ibikoresho by'ikoranabuhanga byizewe

Mu rwego rwo gukora ibikoresho by'ikoranabuhanga, gukora neza no kwizerwa ni ingenzi cyane. Ikoranabuhanga rya Surface Mount (SMT) ryahinduye inganda, rituma habaho gukora ibikoresho by'ikoranabuhanga bito kandi bikora neza cyane. Ariko, bitewe n'ubuhanga bukomeje kwiyongera mu miterere y'ibice n'ibice, kugenzura ubwiza n'imikorere y'ibi bikoresho by'ikoranabuhanga byaragoranye cyane. Aha niho Solder Paste Inspection (SPI) igaragara. Igenzura rya SPI ni inzira y'ingenzi yo kugenzura ubuziranenge muri SMT ifasha mu kubungabunga amahame yo hejuru mu gukora ibikoresho by'ikoranabuhanga. Muri iyi nkuru, tuzasuzuma ibisobanuro birambuye kuriIgenzura rya SPI, akamaro kayo, uburyo ikoreshwa, n'ingaruka zayo ku bwiza rusange bw'ibikoresho by'ikoranabuhanga.

Igenzura rya SPI ni iki? 

Igenzura rya Solder Paste (SPI) ryerekeza ku gikorwa cyo gusuzuma ikoreshwa rya solder paste ku kibaho cyacapwe (PCB) mbere yo gushyiramo ibice by'ikoranabuhanga. Solder paste ni uruvange rw'ifu ya solder flux n'ifu ya solder ikoreshwa mu gukora imiyoboro ya solder hagati y'ibice by'ikoranabuhanga na PCB. Gukoresha neza solder paste ni ingenzi kuko bigira ingaruka ku kwizerwa no gukora neza k'umusaruro wa nyuma. SPI igenzura ko solder paste ikoreshwa neza, mu bwinshi bukwiye, no ahantu hakwiye, bigabanye ibyago byo guhura burundu.

Kuki hakoreshwa igenzura rya SPI mu gukora ibikoresho by'ikoranabuhanga?

1. Kwirinda inenge: SPI igira uruhare runini mu gukumira inenge zikunze kugaragara nko kugabanya ibiraro by’ibikoresho, kudakoresha neza ibikoresho, no kudahuza neza ibice byabyo. Mu kubona ibi bibazo hakiri kare mu gikorwa cyo kubitunganya, SPI ifasha kwirinda kongera gukora no gusana amafaranga menshi.

2. Kurushaho Kwizerwa: Gukoresha neza ifu yo gusoda ni ingenzi mu gukora imiyoboro yizewe ishobora kwihanganira stress ya mekanike n'imikorere y'ubushyuhe. SPI igenzura ko ifu yo gusoda ikoreshwa neza kandi neza, bigatuma igikoresho cy'ikoranabuhanga kirushaho kuba cyiza kandi kirambye.

3. Ikoreshwa ry'Ikiguzi: Gusuzuma no gukemura ibibazo byo gukoresha solder paste mu ntangiriro z'umusaruro birahendutse kuruta gukemura ibibazo nyuma yo gushyiramo ibice cyangwa kubivanga. SPI ifasha mu kugabanya igihe cyo gukora no kugabanya imyanda y'ibikoresho.

4. Gukurikiza amahame ngenderwaho: Inganda nyinshi zisaba kubahiriza amahame ngenderwaho n'amabwiriza yihariye y'ubuziranenge. SPI ifasha abakora ibikoresho kubahiriza aya mahame mu kwemeza ko ikoreshwa rya solder paste ryujuje ibisabwa.

Ni ubuhe buryo bwo kugenzura SPI?

SPI ishobora gukorwa hakoreshejwe uburyo butandukanye, buri bumwe bufite ibyiza byabwo n'imikoreshereze yabwo. Uburyo bw'ibanze burimo:

1.Igenzura ry’amatara ryikora (AOI): Ubu ni bwo buryo busanzwe bwa SPI, bukoresha kamera zifite ubushobozi bwo hejuru n'uburyo bwo gutunganya amashusho kugira ngo harebwe ikoreshwa rya solder paste. Sisitemu za AOI zishobora kubona ibitagenda neza nko kuba solder paste irenze urugero cyangwa idahagije, kudahuza neza, no guhuza. Izi sisitemu zikora neza cyane kandi zishobora gutunganya PCB nyinshi vuba.

2.Isuzuma rya X-ray: Isuzuma rya X-ray rikoreshwa mu kumenya ibibazo bitagaragara n'amaso cyangwa hakoreshejwe uburyo busanzwe bwo kwerekana. Ni ingirakamaro cyane cyane mu gusuzuma imiterere y'imbere ya PCB zifite ibyiciro byinshi no kumenya ibibazo nk'ibiraro byihishe cyangwa icyuho.

3. Igenzura ryakozwe n'intoki: Nubwo ritakunze kugaragara mu nganda zikora ibikoresho byinshi, igenzura ryakozwe n'intoki rishobora gukoreshwa mu nganda nto cyangwa nk'uburyo bw'inyongera. Abagenzuzi bahuguwe basuzuma ikoreshwa rya solder paste kandi bagakoresha ibikoresho nk'indorerwamo zo gukuza kugira ngo bamenye inenge.

4. Igenzura rya Laser: Sisitemu za SPI zikoresha laser zikoresha laser kugira ngo zipime uburebure n'ingano y'ibice bya solder paste. Ubu buryo butanga ibipimo nyabyo kandi bufite akamaro mu gutahura ibibazo bijyanye n'ingano n'ubunini bwa paste.

Ni ibihe bipimo by'ingenzi mu igenzura rya SPI?

Ibipimo byinshi by'ingenzi birasuzumwa mu gihe cyo kugenzura SPI kugira ngo harebwe niba ikoreshwa neza rya solder paste. Ibi bipimo birimo:

1. Ingano y'umushongi w'ibice bya solder: Ingano y'umushongi w'ibice bya solder iri kuri buri pad igomba kuba iri mu rugero rwagenwe. Umushongi mwinshi cyangwa muto cyane ushobora gutera inenge mu ngingo z'umushongi.

2. Ubunini bwa paste: Ubunini bw'urwego rwa paste ya solder bugomba kuba bungana kugira ngo ibice bitose neza kandi bifatanye neza. Ihindagurika ry'ubunini bwa paste rishobora kugira ingaruka ku bwiza bw'ingingo ya solder.

3. Guhuza: Ifu yo gusoda igomba kuba ihuye neza na PCB pads. Kutahuza neza bishobora gutera imiterere mibi y'ingingo zo gusoda no kugira ibibazo byo gushyira ibice byazo mu mwanya wabyo.

4. Gukwirakwiza ifu y'umusemburo: Gukwirakwiza ifu y'umusemburo mu buryo bumwe kuri PCB ni ingenzi kugira ngo ifu y'umusemburo ihore ikora neza. Sisitemu za SPI zisuzuma uburyo ifu y'umusemburo ikwirakwira neza kugira ngo hirindwe ibibazo nk'ubusa cyangwa uruziga.

Ni gute wakwemeza ko icapiro rya Solder Paste rikora neza?

● Umuvuduko wo gukaraba: Umuvuduko w'urugendo rw'icyuma gikase ugena igihe gihari kugira ngo icyuma gikase "gizingire" mu myobo ya stencil no ku dupapuro twa PCB. Ubusanzwe, hakoreshwa imiterere ya mm 25 ku isegonda ariko ibi birahinduka bitewe n'ingano y'imyobo iri muri stencil n'icyuma gikase cyakoreshejwe.

● Umuvuduko wo gukanda: Mu gihe cyo gucapa, ni ngombwa gushyira igitutu gihagije mu burebure bwose bw'icyuma gikase kugira ngo stencil ihanagurwe neza. Igitutu gito cyane gishobora gutera "gusiga" ifu ku gitutu, gupfundika nabi, no kohereza PCB ku buryo butuzuye. Igitutu kinini gishobora gutera "gukura" ifu mu myobo minini, kwangirika cyane ku gitutu no gukase, kandi bishobora gutera "kuva amaraso" ku gitutu hagati ya stencil na PCB. Uburyo busanzwe bwo gushyira igitutu ku gitutu ni garama 500 z'igitutu kuri 25mm z'icyuma gikase.

● Kanda Inguni: Inguni y'icyuma gifata ubusanzwe ishyirwaho na dogere 60 n'ibikoresho bifatwa. Iyo inguni yiyongereye bishobora gutuma "gufata" ibumba ry'icyuma gifata ubudodo riva mu myobo ya stencil bityo ibumba ry'icyuma rigashyirwamo rito cyane. Iyo inguni yagabanutse, bishobora gutuma ibumba ry'icyuma gifata ubudodo risigara kuri stencil nyuma y'uko ibumba rirangije gucapa.

● Umuvuduko wo gutandukanya stencil: Uyu ni umuvuduko PCB ikoresha mu gutandukanya na stencil nyuma yo gucapa. Hagomba gukoreshwa umuvuduko wa milimetero 3 ku isegonda kandi ugengwa n'ingano y'imyobo iri muri stencil. Iyo ibi byihuta cyane, bizatuma icyuma gishongesha kitava mu myobo no mu miterere miremire ikikije imyobo, izwi kandi nka "amatwi y'imbwa".

● Gusukura icyuma gikozwe muri stencil: Imashini icapa ikoresha stencil igomba gusukurwa buri gihe mu gihe cyo kuyikoresha, ibyo bikaba bikorwa n'intoki cyangwa mu buryo bwikora. Imashini icapa ikoresha ikoranabuhanga ifite uburyo bushobora gushyirwaho bwo gusukura stencil nyuma y'umubare uhoraho w'amacapiro hakoreshejwe ibikoresho bidafite lint bishyirwa hamwe n'imiti isukura nka Isopropyl Alcohol (IPA). Ubu buryo bukora imirimo ibiri, iya mbere ni ugusukura igice cyo munsi cya stencil kugira ngo ihagarike imyuka, naho iya kabiri ni ugusukura imyobo hakoreshejwe vacuum kugira ngo ihagarike ifunga.

● Imiterere ya stencil na squeegee: Imashini zo gushushanya n'izicukura bigomba kubikwa neza kandi bigafatwa neza kuko kwangirika kwabyo muri byo bishobora gutera ingaruka zitari zifuzwa. Byombi bigomba gusuzumwa mbere yo kubikoresha no gusukurwa neza nyuma yo kubikoresha, byaba byiza hakoreshejwe uburyo bwo gusukura bwikora kugira ngo ibisigazwa byose bya solder paste bikurweho. Iyo hagaragaye ibyangiritse kuri mashini zo gushushanya cyangwa izicukura, bigomba gusimburwa kugira ngo habeho inzira yizewe kandi ishobora gusubirwamo.

● Gucapa Stroke: Iyi ni intera umuntu ukoresha stencil anyuramo kandi ni ngombwa ko iba nibura mm 20 uvuye ku mwenge uri kure cyane. Intera irenze uwo mwenge uri kure cyane ni ingenzi kugira ngo habeho umwanya uhagije kugira ngo uwo mwenge uzunguruke ku murongo ugaruka kuko uba uri kuzunguruka umushumi w'umushumi utanga imbaraga zo hasi zituma uwo mwenge ujya mu mwenge.

Ni ubuhe bwoko bwa PCB bushobora gucapwa?

Uko byagenda koseikomeye,IMS,guhindagurika gukomeyecyangwaPCB yoroshye(reba ku rubuga rwacu rwaInganda za PCB), niba imbaraga za PCB zidahagije kugira ngo zishyigikire PCB ubwayo nk'uko bisabwa ku murongo wa SMT, uruganda rukora PCB ruzasaba guhinduraUmuyoboro wa SMTcyangwa imodoka itwara ibintu (ikozwe muri Durostone).

Iki ni ikintu cy'ingenzi kugira ngo PCB ifate neza kuri stencil mu gihe cyo gucapa. Iyo PCB, yaba ikomeye, IMS, ihamye cyangwa ikoze neza, idashyigikiwe neza, bishobora gutera inenge mu icapiro, nko gutakaza neza imashini no gushonga. Inkunga za PCB muri rusange zitangwa n'imashini zicapura zifite uburebure buhamye kandi zifite imyanya ishoboka kugira ngo zikore neza. Hariho kandi PCB ihinduka kandi ifite akamaro mu guteranya impande zombi.

PIsuzuma rya Solder Paste ryakuweho (SPI)

Uburyo bwo gucapa ifu ya solder paste ni kimwe mu bice by'ingenzi cyane mu gikorwa cyo guteranya ubuso. Uko inenge yagaragaye kare ni ko bizatwara amafaranga make kuyikosora - itegeko ry'ingirakamaro ryo gusuzuma ni uko ikosa ryagaragaye nyuma yo kongera gukoreshwa rizatwara inshuro 10 z'amafaranga yo kongera gukoreshwa ugereranyije n'ayo yagaragaye mbere yo kongera gukoreshwa - ikosa ryagaragaye nyuma yo gupimwa rizatwara izindi nshuro 10 z'amafaranga yo kongera gukoreshwa. Birumvikana ko uburyo bwo gucapa ifu ya solder paste butanga amahirwe menshi yo kugira inenge kurusha undi muntu uwo ari we wese.Uburyo bwo gukora ikoranabuhanga ryo gushyira ku butaka (SMT)Byongeye kandi, guhinduka ujya kuri solder paste idafite lisansi no gukoresha ibice bito, byongereye uburyo bwo gucapa bugoye. Byagaragaye ko solder paste idafite lisansi idakwirakwira cyangwa ngo "itose" kimwe n'izo solder paste zikozwe mu cyuma. Muri rusange, hakenewe uburyo bwo gucapa bunoze mu buryo budafite lisansi. Ibi byatumye uruganda rukora isuzuma ryikora nyuma yo gucapa. Kugira ngo harebwe uburyo ikorwa, isuzuma ryikora rya solder paste rishobora gukoreshwa kugira ngo harebwe neza aho solder paste ikoreshejwe. Muri RICHFULLJOY, dushobora kubona inenge zimwe na zimwe za solder paste zacapwe, aho umurongo udahagije ushyirwa, aho lisansi ikabije, aho imiterere ihinduka, aho ibura, aho ikoreshwa, aho ishyirwa, n'ibindi byinshi.
