Guangmai Technology tau tshaj lij hauv kev ua SMD LED Chip Soldering Welding Assembly SMT mus rau PCB Service.
LED reflow soldering kub thiab teeb sijhawm
Tom qab reflow soldering ntawm LED teeb hlaws dai, qhov reflow soldering kub yuav tsum tau teeb tsa, txwv tsis pub nws yog qhov yooj yim ua rau pom qhov tshwm sim tuag ntawm ib pawg ntawm cov hlaws teeb thiab ua rau tsis tuaj yeem ua rau poob. Yog li yuav ua li cas thiaj li reflow soldering ua haujlwm tsis zoo thiab ua rau poob yam tsis tsim nyog? GMKJ LED nyob ntawm no rau txhua tus los piav.
1. Tom qab LED reflow soldering kub nkhaus tau hloov kho, kev tsim khoom loj yuav tsum ua tiav tom qab thawj lub rooj tsavxwm tau lees paub thiab qhov ua tau zoo. Nov yog thawj qhov kev lees paub hauv kev tswj hwm lub Hoobkas zoo.
2. LED reflow soldering. Ua ntej ua haujlwm soldering, koj yuav tsum nyeem lub Hoobkas tshwj xeeb ntawm LED teeb hlaws thiab pom nws ntau yam kev ntsuas.
1. Nws nyob ntawm qhov kub tsis kam ntawm LED teeb hlaws ntim cov khoom ntim khoom;
2. Nws nyob ntawm seb cov khoom siv hlau vuam siv hauv paus khoom yog dab tsi, xws li PCB dav dav (fiber board, thiab lwm yam), aluminium substrate, ceramic board, thiab lwm yam;
3. Nws nyob ntawm cov laug, seb nws puas kub lossis kub tsis kam muab tshuaj txhuam, lossis tshuaj txhuam, thiab lwm yam;
4. Nws yuav tsum raug txiav txim siab raws li qhov ua tau zoo ntawm LED cov khoom siv rov ua dua tshiab, nyob ntawm tus naj npawb ntawm thaj chaw kub ntawm LED reflow soldering, tswj ntawm tus ncej ntws tus nqi, kiv cua, thiab ntsuas kub ntawm txhua cheeb tsam.
3. Siv cov kev hloov pauv dav dav ntawm LED teeb hlaws tom qab LED reflow soldering
Qhov kub qis tshaj yog 150-170 degrees, qhov kub siab tshaj yog qhov zoo tshaj 240-245 degrees (qhov kub siab tshaj plaws tuaj yeem hloov kho mus rau 260, yog 245 degrees tuaj yeem yaj tin, tsis hloov mus rau 260), lub sijhawm siab tshaj 220 degrees tuaj yeem tsis tshaj 60 vib nas this, Yog tias qhov kub tau nce, lub sijhawm ntawm 260 degrees tsis tuaj yeem tshaj 10 vib nas this. Yog tias nws yog 7 thaj chaw kub, koj tuaj yeem xa mus rau cov teeb tsa hauv qab no: 160, 170, 175, 180, 190, 210, 245, 220. Yog tias lub teeb ci LED hlaws yog lub lens silicone, BI58SN42 siv tshuaj yaj yeeb yaj kiab, thiab qhov siab tshaj plaws yog 225 degrees Celsius. Yog tias nws yog PC lub lens, rov ua kom zoo dua qub tsis tuaj yeem siv txhua.
Daim duab khoom: Cov laug cam pcb LED hla lub qhov cub rov qab tom qab SMT
Dab tsi GMKJ LED tuaj yeem ua tam sim no:
 |  |  |
| Hlau soldering thiab LED& resistors soldering mus rau pcb cov laug cam | wago hlau txuas txuas txuas thiab sib dhos | Aluminium pcb boards gerber file thiab Altium tsim cov duab kos |
GMKJ LED yog tus kws tshaj lij hauv kev ua cov LED chips:
LED teeb pom kev zoo tom qab siv tas, peb yuav tshuaj xyuas 100% ua ntej khoom xa tuaj.
 |  |
| Cog LED kev loj hlob pcb boards 100% teeb pom kev zoo ntawm kev kuaj ua ntej xa zaub mov | UV LED Teeb pom kev zoo ntawm kev txheeb xyuas ua ntej xa zaub mov |
