Tact chinja 6 × 6 SMTndechimwe chezvigadzirwa zvemagetsi zvinotengeswa zvakanyanya, nekuda kwekushandiswa kwakakura kwezvikumbiro, zvakafarirwa neruzhinji rwevatengi, zvisinei kuti chigadzirwa chakaita sei semunhu akanaka, hapana chakakwana, pane humwe hurema uye. kuperevedza.Pane mamwe matambudziko nechigadzirwa ichi, asi zvakanaka maererano nekushandiswa kwese uye mhando.Zvinetso zvinogona kudzorwa uye kudziviswa, zvakadai sekushandisa uye kugadzirisa.Kushandiswa zvakanaka uye kugadzirisa zvinogona kuita kuti upenyu hurebe.Izvi zvinotevera zvakanyanya nezve TACT chinja 6 × 6 matambudziko akajairika.
Tact switch 6 × 6 SMT zvakajairika matambudziko
Yakanyanya kupikisa kukosha: parizvino, vatengi vazhinji havanyatso kujairana nekukosha kwekupokana kweTACT switch 6 × 6.Kazhinji, kukosha kwekupokana kwekuchinja kwedu kunodzorwa pazasi 30m Ohms, saka kubata kwekuita uye hupenyu hwekuchinja kwakanaka kwazvo, asi mamwe ma switch akanyanya kupikisa kukosha mushure mekupisa kwechoto uye bvunzo yehupenyu.Chii mhedzisiro yekupokana kwakanyanya patACT switch 6 × 6?Kana kushorwa kwakakwira, nzvimbo yekubata ye shrapnel uye PIN PIN ye switch idiki.Iyo diki yekubatanidza nzvimbo inotungamira kune switch isingabatane.Kana iyo switch isina kubatwa, ichave yakaipa.
Naizvozvo, isu tinofanirwa kungwarira nezve kuramba kweiyo switch, shrapnel uye PIN ye electroplating zvinodiwa zvine yakakwira, electroplating yakanaka yekudzivirira kukosha ichave yakaderera.Shandura muyedzo yehupenyu, iyo pamusoro pe shrapnel ichapfeka, kana plating yakaonda, kushorwa kwakakwira, switch yakashata.
Vaviri, kunamatira: yekupedzisira-yakaonda TACT switch 6 × 6 inowanzozivikanwa seyakaonda firimu switch, mutete switch inoda firimu rakatetepa, kuitira kuti uwane mutete chaiwo.Asi yakawanda yefirimu tembiricha kuita hazvina kunaka, mushure mechoto chinodonha chiitiko.Yedu nyanzvi izwi rakati adhesion, chokwadi, iyo firimu viscosity uye yekupinda PI firimu yakanaka kwazvo kutonga kweizvi, kunamatira kwayo i400 g, inopindirana neshanduko yekushandisa, kuti yakareruka sei inodonha, kana yakanyanya kurema ichachinja zvinoenderana neyakagadziriswa. , vagadziri vakawanda kuitira kuchengetedza mutengo wekusarudza mudzimba zvakachipa PI firimu, chinja chiri nyore kwazvo kunamatira matambudziko, Ipa munhu wese kubvunza mugadziri zvakanaka asati atenga.
Vatatu, mushure mechoto haigoni kudzvanya: chinja chakanaka, mushure mekudzoka kwekutsvaira ruzivo haugoni kudzvinyirira, murombo zvikuru.Vatengi vazhinji vari kupindurawo kune dambudziko iri, saka chii chinokonzera?Iyo chigamba switch inotsvedza nePCB, uye PIN inonamirwa kune solder paste.Kana gomba resimbi mesh rakakura zvishoma, solder paste iri nyore kuyerera ichipinda mukati meiyo switch.Kana pane imwe nyika yekunze mukati meiyo switch, ichakanganisa kufamba kwayo.Iyo yakajairika haisi kufamba.Imwe mamiriro nderekuti switch yekuisa chisimbiso kuita haina kunaka, pinda mukati mekuchinja mukati, saka dambudziko rinouya.
Naizvozvo, zvinokurudzirwa kuti vatengi vatarise dambudziko iri mukugadzira.
Chechina, chivharo chakavharwa: mukugadzira maitiro, pachave nekudonha kwevhavha ine mutengi reaction switch.Chivharo chakanaka cheswitch chinobuda sei?Chekutanga pane zvese, isu tinofanirwa kunzwisisa chimiro chekuchinja, chivharo chekuchinja chiri kuseri kwechivharo, iyi miriyoni yemakore ekugara ekugadzira maitiro.
Kana iwe uchizviziva, iwe uchaona kuti chivharo chinogadziriswa neina riveting points pachigadziko.Chero bedzi mapoinzi mana ekutsvedza akasununguka kana nzvimbo dzekutsvedza dzakadzikira kana kuremara mushure mekupisa kwakanyanya, chivharo chinodonha.Chengetedza matambudziko maviri anotevera kudzivirira chivharo, chigadziko chekushandisa tembiricha inodzivirira zvinhu, maviri riveting mapoinzi kune riveting yakagadziriswa, ita basa rakanaka rematambudziko maviri ari pamusoro, dambudziko iri rinogadziriswa zvakakwana.
5. Kunzwa kwemaoko: Vatengi vakawanda vave vachipindura, uye manzwiro emaoko emasampuli anotumirwa nevakawanda vanopa anowirirana zvakanyanya, asi kana zvasvika pakugadzirwa kwehuwandu, kunzwa kwemaoko kwakasiyana.Muchokwadi, dambudziko iri rakajairika, isu tese tinoziva kuti switch inonzwa uye bhatani simba rinodzorwa ne shrapnel.Tinowanzoti shrapnel yakakamurwa kuita phosphorus mhangura shrapnel uye shrapnel yesimbi isina tsvina.Parizvino, vagadziri vakawanda vanosarudza phosphorus mhangura shrapnel kuitira kuchengetedza mutengo.Phosphorus mhangura shrapnel inodhura-inoshanda, icho zvakare chikonzero chekushandiswa zvakanyanya.Asi phosphor mhangura shrapnel mushure mekupisa kwechoto kunoburitsa shanduko, shrinkage yakanyanya kuoma, saka inotungamira mukutadza kunzwa kwemaoko.
Kushandiswa kwesimbi isina tsvina shrapnel hakuzove nedambudziko iri, asi mari yesimbi isina tsvina yakakwira zvakanyanya, zvichiita kuti vagadziri vakawanda vasarudze njodzi yefosforasi mhangura yemhangura, saka pakutenga TACT chinja 6 × 6 inofanira kubvunza mibvunzo yakajeka. .
Nhanhatu, chiedza chinotsikirira kwete conductive: vatengi vakawanda, mukushandiswa kwechigadzirwa kazhinji vakaona kuti bhatani rekudhinda haripinduri, kuva rakaoma zvikuru kudzvinyirira, chigadzirwa chine mhinduro inoshanda.Nekuda kwekuti maswichi edu anoratidzwa kumhepo, zvigadzirwa zvakawanda zvakapedzwa hazvina kuvharwa, uye zvemagetsi zvevatengi zvinoda kupisa kupisa.Mumamiriro ekunze ekunyorova, switch shrapnel iri nyore kuve oxidized, iyo yekubata mashandiro mushure meiyo oxidation haina kunaka sepakutanga, ndiko kuti, kune mwenje wekudhinda kwete conductive dambudziko.
Patinobvisa switch, tinoona kuti pane diki dema pane shrapnel, uye iyi diki nhema kavara ndiko mhedzisiro yeoxidation yeshrapnel.Naizvozvo, zvinokurudzirwa kuti zvigadzirwa zvemagetsi zvatisinga shandise panguva dzakajairwa zvinofanirwa kuiswa munzvimbo yakaoma, uye zvikamu zvemagetsi zvakabhadharwa zvinofanirwa kuve oxidized.
