Cov pob qij txha ntawm FPC cables yog me me. Cov txheej txheem vuam tam sim no hu ua precision vuam. Cov txheej txheem vuam tsoos feem ntau yog phau ntawv welding lossis tsis siv neeg vuam tshuab, tab sis qhov ceev, txheej txheem thiab zoo ntawm ob qho tib si sib txawv ntawm laser vuam. Qhov zoo ntawm vuam yog cuam tshuam nrog qhov zoo ntawm cov khoom. Tom ntej no, cia peb sib piv qhov sib txawv ntawm phau ntawv welding thiab laser vuam.
Tes soldering
1. Ua ntej pasting thiab aligning FPC thiab PCB boards, xyuas cov PCB pads kom smoothness thiab oxidation. Tshem tawm FPC ob sab daim kab xev thiab muab tshuaj txhuam rau saum lub PCB kub ntiv tes. Thov nco ntsoov tias PCB pads yuav tsum xau txog 1.0 hli ntawm cov hlau pins tom qab muab tshuaj txhuam.
2. Soldering: Lub sij hawm siv yog 1-2 vib nas this thiab yuav tsum tau ua raws li kab ntawv dawb rau saum FPC. (Soldering siv sij hawm 1-2S) Lub ntsiab tswj lub sij hawm thiab txoj hauj lwm ntawm lub tin pub thiab luag soldering:.
Plaub qhov tseem ceeb tswj cov ntsiab lus ntawm solder pub thiab luag soldering:
Lub sij hawm: feem ntau pom zoo rub lub sij hawm soldering raws li qhov ntev ntawm cov hlau taub hau 3S suav, txog 4 ~ 10S.
Kub: ob puas thiab cuaj caum degrees rau peb puas thiab kaum degrees.
Tin feeding txoj hauj lwm: tin feeding txoj hauj lwm yog qhov zoo tshaj plaws nyob rau hauv lub soldering hlau taub ntawm lub qis txoj hauj lwm, txoj hauj lwm yog biased ntawm lub ncoo.
Lub zog: lub taub hau ntawm cov hlau nplaum thiab cov khoom ua haujlwm sib cuag lub zog: lub taub hau hlau thiab cov khoom ua haujlwm sib cuag kom ua rau lub siab me ntsis, lub hauv paus ntsiab lus tsis ua rau kev puas tsuaj rau FPC kub ntiv tes.
3. Kev tshuaj xyuas tus kheej tom qab soldering: 45-degree soj ntsuam. Tom qab soldering, koj yuav tsum siv sijhawm 1-2 vib nas this los kuaj xyuas tus kheej kom pom tias muaj qhov tsis xws luag xws li cov khoom cuav, kev sib txuas txuas ntxiv lossis kev sib txawv.
Laser soldering txheej txheem:
1, lub pob brazing tau dov lub nozzle, lub nozzle daig nyob rau hauv lub unmelted brazing pob.
2, lub nozzle pib sau cov nitrogen.
3, thaum lub siab nitrogen nce mus txog tus nqi ua ntej. Laser irradiation pib, cov txheej txheem brazing pob melting pib.
4, Cov khoom siv brazing pob melts thiab ejected nyob rau hauv lub siab ntawm nitrogen; 4, Cov khoom siv brazing pob melts thiab ejected nyob rau hauv lub siab ntawm nitrogen.
5, Brazing cov ntaub ntawv pob hu rau lub ncoo, tsim lub pob, lub ncoo tsis tas yuav tsum tau preheated.
Qhov zoo ntawm kev siv laser solder pob tsuag vuam tshuab:
(1) Lub zog kub, qis tshav kub tawm, me me thermal deformation, nqaim melting cheeb tsam thiab tshav kub loj.
(2) Vim tias qhov txias txias ceev, cov qauv vuam zoo thiab kev sib koom ua haujlwm zoo.
(3) Vim nws tsis yog kev sib cuag welding thiab tsis siv electrodes, nws txuag lub sijhawm ua haujlwm.
(4) Lub vuam ceev ceev thiab tuaj yeem ua tiav hauv 0.2 vib nas this.
Tom qab saib phau ntawv welding thiab laser vuam, kuv ntseeg tias txhua tus paub tias txoj kev vuam muaj qhov zoo dua. Laser solder pob welding yog tsim rau high-precision vuam nrog qhov tseeb ntawm ± 10um thiab qhov sib txawv yam tsawg kawg nkaus ntawm 100um. Muaj ntau yam ntawm cov khoom siv los xaiv, nrog qhov tsawg kawg nkaus txoj kab uas hla ntawm 70um. Siv rau cov khoom siv hlau xws li tin, kub, thiab nyiaj, tus nqi tawm los yog ntau dua 99%. Lub laser soldering tshuab yog tsim rau uninterrupted precision vuam txheej txheem.
