Uchishandisa Flat Musoro Screwdriver
Screwdriver ndicho chishandiso chakajairika chinogona kuwanikwa mune chero chishandiso. Kunyangwe zvakagadzirwa kujoina, tinogona kuzvishandisa nechinangwa chakapesana futi. Sezvineiwo, yakati sandara musoro screwdriver isarudzo yeyakakura musoro pamusoro penzvimbo. Zvisinei, aya matanho mashoma ane mukana wekutungamira kune imwe yakanaka nzira.Nhanho 1: Bvisa iyo Tip
Bata bata musoro screwdriver uye kwiza musoro wayo nechidimbu chemucheka wakachena uye wakaoma. Izvo zvichave nechokwadi icho hapana oxide kana ngura zvinosara pamusoro wechikamu. Heino chidimbu! Sarudza chekare sikurudhiraivha muhombodo yako. Sezvo iyo screwdriver ichave yakanyanya kudziyirwa uye gare gare yakatonhora pasi, inowanzo kuve yakasvibiswa.
Nhanho 2: Ipise
Zve kudziisa iyo screwdriver, propane torch ndiyo yakanyanya kunaka sarudzo. Inogona kugadzira murazvo kusvika 2000 kusvika 2250 degrees Fahrenheit. Kusiyana tochi yetani iyo inoshandiswa kusungira mapaipi emhangura, propane torch inoburitsa murazvo wakawanda. Zvakananga bata screwdriver mumurazvo we tochi yekunamatira uye mirira kusvikira simbi yashanduka kuita tsvuku. Ita chiito ichi sepedyo nguva sezvinobvira kune soldering.
Nhanho 3: Sungunusa iyo Solder Pasi
Iye zvino nguva yasvika yekubata iyo solder neepipi yeanopisa screwdriver. Asi iwe unofanirwa kuve wakangwarira kwazvo kuisa kupisa chete pane yaunoda solder mubatanidzwa, kwete zvimwe zvikamu zvedunhu. Iyo yakazara yakazara pamusoro ndiyo shamwari yakanakisa yeiri basa. Ita shuwa kuti pcb yakaiswa zvakaenzana pamusoro. Wobva waedza kutsvaga iyo yepamusoro yeiyo solder kana iyo bubble. Kubata zvakapfava kwakaringana kugadzira kudikanwa kwekubatana pakati pechidimbu che screwdriver uye bubble. Gare gare nyorovera pasi uye iyo yakasimba solder inotanga kunyungudika.
Nhanho 4: Bvisa iyo Solder
Paunenge iwe wabudirira kunyungudutsa iyo solder, iwe unofanirwa kunyatsovabvisa kubva paPCB. Zvekare, iyo screwdriver iri mukununura! Bata iyo screwdriver iyo inofanirwa kunyanya kutonhodza iko zvino uye kuibata neiyo solder. Nenguva isipi iyo solder inonamira kune iyo screwdriver. Unogona kushandisa imwe screwdriver kana iyo yapfuura isingakwanise kutonhorera.
Nhanho 5: Tsvaira iyo Tip
Zvakare tora propane torch uye upise. Bata screwdriver mumoto. Wobva watsvaira pamusoro nejira. Saka iyo yakasara solder pane screwdriver pamusoro inogona kucheneswa zvakafanana nzira yaunosuka iron yesimbi.
ZveSavaging Delicate Components kubva kuElectric Circuitry
Iwe unogona zvechokwadi bvisa solder kubva chero pcbp nenzira iyoyo yambotaurwa. Asi kune mamwe maburi. Iko kupisa kwauri kuisa pane iro bhodhi kunogona kukuvadza zvimwe zvinonetsa zvikamu pane iro bhodhi. Ndosaka chimwe chinhu chiri kudiwa icho chinogona kubvisa zvakachengeteka izvo zvinhu. Kunyangwe mune izvi maitiro, kupisa kunokosha. Asi humwe hunyanzvi hunoshandiswa kuchengetedza kutonga pamusoro pekupisa uye kupatsanura zvakakomberedza.
1. NeKudziisa Imwe Temu
Kwete hazvo kuti iwe unopisa matunhu ese echinhu panguva. Unogona kuisa kupisa imwe neimwe. Iyi nzira inoshanda zvakanyanya kana iwe uchifanira kubata nezvakaomesesa zvinhu. Yakaderera wattage simbi inogona kushandiswa kupa kupisa. Kunze kwezvo, kuisa chinodziya padhuze nechinhu chacho kunogona kushanda zvakanyanya kubvisa kupisa kusingadiwe.
2. Kushandisa Hot Air Gun uye kubvisa Pump
Mhepo inopisa pfuti inogona kuridza mweya unopisa kune iyo PCB uye pakupedzisira inogona kuita kuti iyo solder inopisa zvakakwana. Kushandisa pfuti yemhepo inopisa ndiyo imwe nzira yehunyanzvi yekupedzisa basa. Asi vakomana ava vanowanzoisa oxidize zvimwe zvinhu zvesimbi padunhu. Ndosaka kushandisa nitrogen gasi kwakachengeteka. Kunyange maturusi aya anogona kufuridza mweya unopisa kumajoini asi iyo solder inosunungura iyo pcb yaida kubviswa. Pombi yakagadzirirwa yekukweva kana inonamira inodiwa kuti ubvise zvakachengeteka. Kushandisa zvishandiso izvi kuchaona kuti hapana chimwe chinhu chinobatwa kana kusavharwa kusingadiwe kwesoder kunoitika.
3. Uchishandisa Quad Flat Mapakeji kuti ubvise Zvimwe Zvakaomesesa Zvikamu
Kana iwe uchida kununura IC kubva paPCB, hapana chikonzero chekushandisa iyo simbi inonamira yakananga. Ehezve, iwe haugone kupisa ese ma terminals eiyo IC kamwechete nesimbi yekunamatira. Kunyangwe kushandisa iyo inopisa mweya pfuti zvisina tsarukano haigone kuunza chaunoda mhedzisiro. Mune ino mamiriro, iwe unofanirwa kushandisa Quad yakati sandara pasuru. Iyo yekutanga kuvaka kweQFP iri nyore. Iyo ine yakatetepa tungamira iyo yakanyatso kurongedzwa pamwe uye mana matete masvingo anoita seanodziya kupisa. Iyo ine chitubu system inobata iyo IC kumusoro kumusoro nekukurumidza kana iyo solder yasvika kune yakasviba nyika. Mushure mekumisa zvakanaka QFP, iwe unofanirwa kufuridza mweya unopisa kubva kune inopisa mweya pfuti. Sezvo kupisa kunovhara munzvimbo inodiwa yemadziro matete, iyo solder munzvimbo iyoyo inokurumidza kugamuchira kupisa. Munguva pfupi iwe wasununguka kudhonza iyo IC uchishandisa nzira yekuchera. Imwe QFC ine yakawedzera padding inodzivirira mamwe matunhu edunhu kubva pakuve ari ega.
Brute Force Maitiro
Kana iwe uchifunga kuti iyo PCB yakura zvakakwana uye haichakwanise kushandisa imwezve, unogona kushandisa imwe brute simba maitiro ayo anogona kukubatsira iwe kununura izvo zvinhu. Tarisa ivo kunze!1. Cheka zviteshi
Unogona kucheka zviteshi zvezvinhu zvisingadiwe uye wozvidhonza. Shandisa reza reza pabasa iri. Kunze kwezvo, a vice-grip inogona kubatsira yakawanda kuputsa iyo solder chisungo uye kudhonza icho chinhu. Asi chenjera ruoko rwako uchishandisa simba. Zvirinani kupfeka magirovhosi.
2. Hard Tap pane Chero Flat Surface
Izvi zvingaite kunge zvinonakidza asi kurovera bhodhi kune yakaoma nzvimbo ndiyo yekupedzisira sarudzo yekutyora solder mubatanidzwa. Kana iwe usiri kuda bhodhi asi izvo chete zvinoriumba, unogona kuenda kune iyi nzira. Kuvhunduka kwakasimba kwekukanganisa kunogona kuputsa iyo solder uye kukonzeresa kuti chinhu chacho chisununguke.
Bottom Line
Parizvino iwe unoziva kubvisa solder isina iron yesimbi. Haisi nzungu yakaoma kutsemuka. Kunyangwe mune dzimwe nguva kushandisa iron yesimbi haina kuchengetedzeka. Asi rangarira chero nzira yaunotora, gara uchiita shuwa kuti urikushanda panzvimbo yakatetepa uye usabata iyo inonyungudika solder neruoko rusina chinhu.
Ini ndini Joost Nusselder, muvambi weZvishandiso Chiremba, mushambadzi wemukati, uye baba. Ini ndinoda kuyedza michina mitsva, uye pamwe nechikwata changu ndanga ndichigadzira zvakadzama blog zvinyorwa kubva 2016 kubatsira vaverengi vakavimbika nematurusi & matipi ekugadzira.
