suma:
Chip resistors zvinhu zvakakosha zvinoshandiswa mumidziyo yakawanda yemagetsi kufambisa kwakaringana kuyerera uye kuramba. Nekudaro, senge chero chimwe chikamu chemagetsi, chip resistors inogona kusangana nemamwe matambudziko panguva yekushambadzira.Mune ino blog, isu tichakurukura matambudziko akajairika kana soldering chip resistors, kusanganisira kukuvadzwa kubva kusurges, kuramba zvikanganiso kubva kune solder makatsemuka, resistor vulcanization, uye kukuvadzwa kubva pakuremedza.
1. Kuwedzera kukuvadza kune gobvu firimu chip resistors:
Kuwedzera, kuwedzera kamwe kamwe mumagetsi, kunogona kukanganisa zvakanyanya kuita uye kusimba kweiyo gobvu firimu chip resistors. Kana kuvhiya kukaitika, simba rakawandisa rinogona kuyerera kuburikidza neanopikisa, zvichikonzera kupisa uye pakupedzisira kukuvadza. Kukuvadzwa uku kunozviratidza seshanduko mukupokana kukosha kana kutotadza zvachose kweanopikisa. Naizvozvo, zvakakosha kutora matanho ekuzvidzivirira kubva pakuvhiya panguva yewelding.
Kuti uderedze njodzi yekukuvara kunokonzerwa nekuvhiya, funga kushandisa mudziyo wekudzivirira wekuvhiya kana suurge suppressor. Midziyo iyi inonyatso kutsausa yakawandisa voltage kure neiyo chip resistor, nekudaro ichidzivirira kubva kunjodzi inogona kuitika. Zvakare, ita shuwa kuti mudziyo wako wewelding wakadzikwa zvakanaka kudzivirira kuvhiya kuti kurege kuitika.
2. Kuramba kukanganisa kwe chip resistors kunokonzerwa nekutsemuka kwewelding:
Munguva yekushambadzira, kuputika kunogona kuumba mu chip resistors, zvichikonzera kukanganisa kukanganisa. Izvi zvinoputika zvinowanzove zvisingaoneki kune ziso uye zvinogona kukanganisa kushamwaridzana kwemagetsi pakati pemapedhi ekupedzisira uye chinhu chinopikisa, zvichiita kuti zvive zvisina kururama kupikisa maitiro. Somugumisiro, kushanda kwese kwechigadzirwa chemagetsi kunogona kukanganiswa.
Kuti uderedze zvikanganiso zvekudzivirira zvinokonzerwa nekutsemuka kwewelding, matanho akati wandei ekudzivirira anogona kutorwa. Chekutanga, kuenzanisa iyo welding process paramita kune chaiyo zvinodiwa zve chip resistor kunobatsira kudzikisira njodzi yekutsemuka. Pamusoro pezvo, matekiniki ekufungidzira epamusoro akadai sekuongorora kweX-ray anogona kuona makatsemuka asati akonzera kukuvara kwakanyanya. Kuongororwa kwehunhu kunofanirwa kuitwa nguva nenguva kuona uye kurasa chip resistors chakakanganiswa nekutsemuka kwe solder.
3. Vulcanization of resistors:
Vulcanization nderimwe dambudziko rinosangana panguva yekushambadzira kwechip resistors. Inoreva maitiro ayo anopikisa zvinhu zvinopinda shanduko yemakemikari nekuda kwekuratidzwa kwenguva refu kwekupisa kwakanyanya kunogadzirwa panguva yewelding. Sulfidation inogona kukonzera kudonha mukupokana, zvichiita kuti resistor isakodzere kushandiswa kana kuita kuti dunhu rishande zvisina kunaka.
Kuti udzivise sulfidation, zvakakosha kukwidziridza iyo soldering process paramita senge tembiricha uye nguva yekuona kuti haipfuure iyo yakakurudzirwa miganho yechip resistors. Uye zvakare, kushandisa radiator kana kutonhora sisitimu kunogona kubatsira kudzima kupisa kwakanyanya panguva yewelding uye kuderedza mukana wevulcanization.
4. Kukuvadzwa kunokonzerwa nekuremedza:
Rimwe dambudziko rakajairika rinogona kumuka panguva yekutengesa chip resistors kukuvara kunokonzerwa nekuremedza. Chip resistors inogona kukuvadzwa kana kukundikana zvachose kana ichiiswa kune yakakwira mafungu anodarika iwo epamusoro ratings. Kukuvadzwa kunokonzerwa nekuremedza kunogona kuratidzika sekuchinja kukosha kwekupokana, kuramba kupera simba, kana kukuvara kwemuviri.
Kuti udzivise kukuvadzwa kubva pakuremedza, ma chip resistors anofanirwa kusarudzwa zvine mwero wakakodzera wesimba kubata iyo inotarisirwa ikozvino. Kunzwisisa zvinodiwa nemagetsi pachikumbiro chako uye kuita maverengero chaiwo kunogona kubatsira kudzivirira kuwandisa chip resistors panguva yekutengesa.
Mukupedzisa:
Soldering chip resistors inoda kunyatsotariswa kwezvinhu zvakasiyana-siyana kuti ive nechokwadi chekushanda kwakakodzera uye hupenyu hurefu. Nekugadzirisa nyaya dzakakurukurwa mubhurogi rino, kureva kukuvadzwa kunokonzerwa nekuvhiyiwa, kukanganisa kukanganisa kunokonzerwa nekutsemuka kwe solder, resistor sulfuration, uye kukuvadzwa kunokonzerwa nekuremerwa, vagadziri uye vanoda zvemagetsi vanogona kuvandudza kuvimbika uye kushanda kwemidziyo yavo yemagetsi. Matanho ekudzivirira akadai sekushandisa midziyo yekudzivirira yekuvhiya, tekinoroji yekuona kuputika, optimizing soldering paramita, uye kusarudza maresitorendi ane akakodzera magetsi ratings anogona kuderedza zvakanyanya kuitika kwematambudziko aya, nekudaro kuvandudza kunaka uye kushanda kwemidziyo yemagetsi uchishandisa chip resistors.
