Hluav taws xob soldering hlau yuav tsum tau rau cov khoom sib dhos thiab disassembly.
Kev npaj ua ntej vuam
1. Tshem tawm cov oxide txheej thiab tshem tawm cov txheej oxide kom lub hau ntawm cov hlau soldering tau yooj yim dipped nyob rau hauv solder thaum soldering. Ua ntej siv hluav taws xob soldering hlau, siv ib rab riam los yog cov ntaub ntawv maj mam tshem tawm cov oxide txheej ntawm qhov kawg ntawm cov hlau soldering. Tom qab cov txheej txheem oxide raug tshem tawm, cov hlau yuav raug nthuav tawm. (Cov phooj ywg uas muaj tus nplaig zoo tuaj yeem yaim, Kuv tsis muaj qhov tsis pom zoo)
2. Dip hauv flux. Raws li pom nyob rau hauv daim duab b, tom qab lub oxide txheej ntawm lub soldering hlau taub raug tshem tawm, lub hwj chim ntawm lub soldering hlau kom sov lub taub hau ntawm lub soldering hlau, thiab ces dilute lub ntsis ntawm lub soldering hlau nyob rau hauv rosin (nws muaj nyob rau hauv lub electronics. ua lag luam, tsis txhob mus rau tom khw zaub), thiab koj yuav pom rosin vapor ntawm lub ntsis ntawm cov hlau soldering. (Cov neeg mob uas muaj obsessive-compulsive tsis meej tuaj yeem kuaj qhov kub ntawm lawv lub ntsej muag. Thaum kuv tseem yog menyuam yaus, txhua zaus kuv txiv soldered lub rooj tsavxwm Circuit Court ntawm cov chaw taws teeb tswj nrog cov hlau soldering, kuv xav sim qhov ntsuas kub ntawm cov pa luam yeeb yaj kiab)
Lub luag hauj lwm ntawm rosin yog los tiv thaiv oxidation ntawm lub ntsis ntawm cov hlau soldering ntawm qhov kub thiab txias, thiab txhim khu lub fluidity ntawm solder, ua kom yooj yim rau solder.
3. Dai tin. Thaum lub hau ntawm cov hlau soldering yog dipped nyob rau hauv rosin thiab ncav cuag ib tug txaus kub, rosin vapor yuav tawm los ntawm lub taub hau ntawm lub soldering hlau, thov solder mus rau lub taub hau ntawm lub taub hau ntawm soldering hlau, thiab siv ib tug txheej ntawm solder mus rau lub taub hau ntawm soldering hlau. soldering hlau taub.
Qhov zoo ntawm tinning lub ntsis ntawm cov hlau soldering yog los tiv thaiv lub ntsis ntawm cov hlau soldering los ntawm oxidation thiab ua kom yooj yim rau solder lub Cheebtsam. Hlawv dub thiab oxidizing, nws yog ib qho nyuaj rau solder Cheebtsam. Lub sijhawm no, nws yog ib qho tsim nyog yuav tsum tau khawb tawm cov oxide txheej thiab tom qab ntawd dai tin siv nws. Yog li ntawd, thaum lub soldering hlau tsis siv rau lub sij hawm ntev, lub hwj chim mov yuav tsum tau unplugged los mus tiv thaiv lub soldering hlau los ntawm "hlawv mus rau tuag".
4. Vuam ntawm cov khoom
Thaum soldering Cheebtsam, ua ntej maj mam muab tshem tawm cov oxide txheej ntawm cov pins ntawm lub Cheebtsam yuav tsum tau soldered, ces energize lub soldering hlau, dipped nyob rau hauv rosin tom qab cua sov, thaum kub ntawm lub soldering hlau taub yog txaus, tig lub soldering hlau taub. ntawm lub kaum sab xis 45 ° Nias rau ntawm daim ntawv tooj liab ntawm ib sab ntawm cov pins ntawm cov khoom siv los ua cov khoom siv rau ntawm lub rooj tsav xwm luam tawm, thiab tom qab ntawd kov cov hlau nplaum rau ntawm qhov kawg ntawm cov hlau soldering. Tom qab cov hlau nplaum melts, nws yuav ua kua thiab ntws ncig cov pins ntawm cov khoom. Thaum lub solder yog qhib, lub solder txias yuav welding cov tivthaiv pins thiab tooj liab ntawv ci ntawm lub luam Circuit Court board ua ke.
Thaum soldering Cheebtsam, soldering hlau taub yuav tsum tsis txhob nyob rau hauv kev sib cuag nrog lub luam Circuit Court board thiab Cheebtsam ntev dhau lawm, thiaj li tsis mus ua puas lub Circuit Court board thiab cov khoom. Cov txheej txheem vuam yuav tsum ua kom tiav hauv 1.5 mus rau 4 vib nas this. Lub solder pob qij txha yuav tsum du thiab cov solder yuav tsum tau muab sib npaug. (Tus qub tsav tsheb coj kuv)
5. Disassembly ntawm cov khoom
Thaum disassembling cov khoom ntawm lub rooj tsav xwm luam tawm, siv lub hau ntawm cov hluav taws xob soldering hlau los kov cov pob qij txha ntawm cov khoom siv pins. Tom qab lub solder ntawm lub solder pob qij txha melts, rub tawm cov tivthaiv pins ntawm lwm sab ntawm lub Circuit Court board. , thiab ces solder lwm tus pin nyob rau hauv tib txoj kev. Txoj kev no yog yooj yim heev rau disassemble Cheebtsam nrog tsawg dua 3 pins, tab sis nws yog nyuaj rau disassemble Cheebtsam nrog ntau tshaj 4 pins (xws li integrated circuits).
Niaj hnub no, kev ntim khoom ntawm kev sib xyaw ua ke yog qhov muag heev. Yuav ua li cas ib tug zoo nkauj me ntxhais txaus siab rau solder?
Txhawm rau tshem tawm cov khoom uas muaj ntau tshaj 4 tus pins, koj tuaj yeem siv cov tin-absorbing hluav taws xob soldering hlau, los yog koj tuaj yeem siv lub tshuab hluav taws xob zoo tib yam kom tshem tawm nrog kev pab los ntawm lub tes tsho stainless hlau hollow lub tes tsho lossis rab koob txhaj tshuaj (muaj nyob rau hauv kev lag luam hluav taws xob. , thiab koj tuaj yeem siv ib qho rau kev txhaj tshuaj).
Txoj kev disassembly ntawm ntau tus pin Cheebtsam yog kov cov sib koom ua ke ntawm ib tus pin ntawm cov khoom siv nrog lub hau ntawm cov hlau. Thaum lub solder ntawm lub solder sib koom ntawm tus pin yog melted, muab ib tug syringe koob ntawm qhov tsim nyog loj ntawm tus pin thiab tig nws kom lub ntsiab tivthaiv pins yog sib cais los ntawm tooj liab ntawv ci ntawm lub Circuit Court board, thiab ces lub taub hau ntawm tus pin. cov hlau nplaum raug muab tshem tawm, thiab rab koob ntawm lub koob txhaj tshuaj yog rub tawm tom qab, yog li cov khoom siv pins tau muab cais tawm ntawm cov ntawv ci tooj liab ntawm lub rooj tsav xwm luam tawm, thiab tom qab ntawd cov khoom sib cais los ntawm tib txoj kev. Lwm cov pins raug cais los ntawm cov ntawv luam tawm hauv Circuit Court board tooj liab ntawv ci, thiab thaum kawg cov khoom tuaj yeem rub tawm ntawm lub rooj tsav xwm Circuit Court.
