Yuav ua li cas siv ib tug soldering hlau thawj zaug - yuav ua li cas siv ib tug tshiab soldering hlau
Tshiab soldering hlau thawj zaug siv, cua sov rau thaum pib ntawm melting solder hlau yuav tsum tau muab tso rau ntawm lub taub hau soldering kom cia lub solder melted nyob rau hauv lub hlau taub hau nto, tiv thaiv lub taub hau hlau oxidation tsis nyob rau hauv lub tin. Kuj tseem tuaj yeem coated nrog me ntsis solder paste lossis rosin. Tom qab qhov kev kho mob no, lub taub hau hlau yog yooj yim heev rau ntawm lub tin, yuav tsis muaj "tin pob" co hauv qhov xwm txheej. Thib ob, txhawm rau vuam cov khoom, thawj zaug ua rau kev kho oxidation, yog siv rab riam los txhuam kom huv si saum npoo ntawm oxidized txheej ntawm welded, coated nrog me ntsis solder paste lossis rosin, thiab tom qab ntawd tib lub sijhawm, solder hlau thiab soldering hlau taub hau nyob rau hauv welded qhov chaw, melting me ntsis ntawm solder hlau, nws yuav tau welding qhov zoo heev.
Muaj ob hom ntawm cov khoom siv hlau taub hau, lub taub hau zoo tib yam yog xaiv tooj liab raws li substrate; Lub neej ntev lub taub hau yog lub taub hau hlau plating, uas yog, nyob rau hauv tooj liab nto plated nrog cov hlau ntshiab los yog npib tsib xee, nws lub neej zoo li lub taub hau zoo tib yam li nees nkaum npaug siab dua, thiab tsis yooj yim rau deformation. Lub soldering hlau taub hau tin noj cov kauj ruam yog raws li nram no.
① Xuab zeb los yog txhuam. Ordinary lub taub hau tuaj yeem ua ntej siv cov ntawv xuab zeb rau cov xuab zeb los yog cov ntaub ntawv, sanding qhov ntev ntawm qhov siab ntawm beveled nto me ntsis ntev, yuav tsum tau ceev faj, kom txog thaum lub dav hlau huv si, du zoo. Tom qab ntawd siv ib daim ntaub huv, qhuav los so. Yog hais tias lub neej ntev lub taub hau tsis tuaj yeem sanded los yog ua ntaub ntawv, tsuas yog nrog ib tug huv, qhuav ntaub sassafras.
② Noj tin. Npaj ib lub thawv me me ntawm rosin (cov xaim hlau muaj cov rosin, tab sis cov nyiaj tsawg dhau, tsis yooj yim rau noj tin), tig lub hwj chim ntsaws, tos ob peb lub sij hawm tom qab lub taub hau ntawm cov hlau soldering yuav kub, siv cov soldering. hlau taub dipped nyob rau hauv kov nrog rosin los kwv yees qhov kub thiab txias. Tsuas yog tuaj yeem yaj rosin, tias qhov kub thiab txias tseem qis; rosin dawb pa luam yeeb thiab hlau taub hau ntshav liab loj, tias qhov kub thiab txias heev; tsuas yog rosin tuaj yeem yaj sai sai thiab tsis muaj pa taws ntau, qhov ntsuas kub zoo tshaj plaws. Thaum qhov kub ntawm lub taub hau ntawm lub taub hau mus txog qhov zoo tshaj plaws, tusyees ua kom lub taub hau taub hau dipped hauv rosin. Lub soldering hlau dipped nyob rau hauv rosin yuav tsum sai sai yaj lub solder hlau nyob rau hauv lub soldering hlau ncej phaj los ua ib tug loj soldering point (thiab ces ntxiv ib me ntsis rosin), lub taub hau hlau soldering dua submerged los tig lub soldering point kom txog rau thaum lub soldering hlau taub hau polished. ib feem ntawm tag nrho uniformly noj lub tin.
③ Kev laus. Tom qab soldering hlau taub hau noj tin, lub soldering hlau yuav tsum tau aging. Kev laus tsis yog siv cov hlau soldering rau lub sij hawm rau soldering, kom nws txuas ntxiv rau lub zog cua sov rau ib ntus, thiab tom qab ntawd tshem tawm cov hlua hluav taws xob, muab tso rau hauv cov hlau soldering ntawm lub txee kom nws txias lawm. Kev laus tuaj yeem txuas ntxiv lub neej ntawm lub taub hau hlau thiab cov tub ntxhais hlau, tshwj xeeb tshaj yog cov hlau tshiab thiab cov tub ntxhais hlau. Noj tin, aging tom qab soldering hlau, tom qab siv tau ib txwm.
Yog hais tias siv cov hlau soldering ib txwm, nyob rau hauv ib puag ncig tshiab ntawm lub zog vuam ua ntej, yuav tsum tau xyuas seb lub taub hau hlau "hlawv" los yog "chaw nres nkoj mutilation" thiab lwm yam tshwm sim. "Hlawv" yog hais txog lub taub hau ntawm lub taub hau kom noj cov tin qhov chaw tau oxidized, tig mus rau hauv lub taub hau dub, tsis dipped nyob rau hauv tin los yog dipped nyob rau hauv tin muaj peev xwm tsis zoo heev; "chaw nres nkoj mutilation" yog hais txog kev ua hauj lwm nto convex thiab concave deformation los yog tawg thiab lwm yam. Ob qhov xwm txheej no yuav tsum rov ua lub taub hau hlau.
