Soldering thiab disassembly ntawm cov khoom yuav tsum tau hluav taws xob soldering hlau
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.
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 lub 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 ntawv, thiab tom qab ntawd kov cov hlua hlau mus rau 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).
