UV LED PCB: Yakazara Tekinoroji Yekutungamira kune Professional Zvishandiso

Chii chinonzi UV LED PCB Technology

UV LED PCB inoreva akadhindwa akadhindwa edunhu mabhodhi akagadzirwa kutyaira uye kutsigira ultraviolet chiedza-emitting diodes mhiri UV-A (315-400nm), UV-B (280-315nm), uye UV-C (200-280nm) wavelength siyana. Aya mabhodhi edunhu anoshanda sehwaro hweUV kurapa masisitimu, yekurapa phototherapy michina, sterilization zvishandiso, uye maindasitiri ekufumura michina.

Kusiyana nemaPCB e LED akajairwa , mabhodhi edunhu akadhindwa e UV LED anofanirwa kugadzirisa huwandu hwakanyanya hwekupisa, zvinodiwa zvekutonga simba zvakanyanya, uye zvinodiwa zvekugadzikana kwema wavelength zvinokanganisa zvakananga mashandiro ekushandisa uye hupenyu hwechikamu.

UV LED PCB Mamiriro uye Kushanda Nheyo

Basic Structure Components

Iyo UV LED PCB inowanzo sanganisira matatu akasanganiswa akaturikidzana anoshanda pamwechete kuti awane kuita kwakaringana. Iyo substrate layer inoshandisa aruminiyamu-yakavakirwa zvinhu, ceramic substrates, kana copper-core zvivakwa zvakasarudzirwa yepamusoro yekupisa yekupisa zvivakwa. Iyo solder mask uye inovhenekera maseru inoda UV-resistant formulations kudzivirira kudzikisira uye kuchengetedza kugona kwekuona pasi pekuenderera mberi kweultraviolet.

Working Principle

Nheyo yekushanda inosanganisira magetsi anoyerera kuburikidza nemazvo-akagadzirwa emhangura anoteedzera kune simba LED machipisi, ayo anoshandura simba remagetsi kuita ultraviolet photons. Iyo UV LED PCB panguva imwe chete inobata kugovera kwemagetsi uku ichiitisa tsvina kupisa kure nekusangana, ichichengetedza yakakwana tembiricha yekushanda iri pasi pe85 ° C kuita kwakavimbika.

Yakakosha Dhizaini Mafungiro eUV LED PCBs

Thermal Management Architecture

Thermal manejimendi inomiririra yakanyanya kukosha dhizaini dhizaini muUV LED PCB kusimudzira. Tembiricha yejunction inokanganisa zvakananga zvese zviri zviviri kubuda kwechiedza uye hupenyu hwekushanda, zvinoda zvivakwa zvinopisa zvinosanganisa substrate zvinhu zvine thermal conductivity inopfuura 2 W/m·K. MaAluminium substrates anowanzo kupa 1.5-3 W/m·K, ukuwo maceramic sarudzo akadai sealuminum nitride achiunza hunhu hunodarika 20 W/m·K kune-high-power application.

Nzira dzekuparadza kupisa dzinofanira kuderedza kuramba kupisa pachinhu chimwe nechimwe kubva pakubatana kwe LED kuburikidza ne substrate kusvika pakupisa kwekunze. Magadzirirwo e UV LED PCB epamusoro anosanganisira ma thermal vias, tekinoroji ye copper coin, kana direct bonded copper layers kuti awedzere kushanda zvakanaka kwekupisa.

Magadzirirwo eMagetsi uye Ikozvino Kugovera

Iyo yemagetsi dhizaini yeUV LED PCB inoda yakazvimiririra mutyairi nzira kune yega yega LED kana tambo ye LED kudzivirira kusaenzana kwazvino. Copper trace ukobvu kazhinji inotsanangura huremu hwemhangura hushoma 2 oz, iine mitsetse yakafara uye mapfupi enzira ekudzikisa kurasikirwa kwekupokana. Simba rekupa decoupling uye dhizaini yepasi ndege inoderedza kudzoka nzira impedance uchichengetedza electromagnetic kuenderana.

Kusarudzwa kwezvinhu zveUV Applications

Kusarudzwa kwezvinhu zveUV LED PCBs kunogadzirisa matambudziko akasiyana anounzwa neultraviolet radiation kuratidzwa. Iyo solder mask inofanirwa kuramba kusvibiswa kwepikicha uchishandisa yakasarudzika UV-inodzivirira maumbirwo ayo anodzivirira kutsvuka uye kuparara kwemuchina. Dielectric insulation layers inoenzanisa thermal conductivity pakati pe2-5 W/m · K zvichipesana nemagetsi ekuzviparadzanisa nevamwe, nehukobvu hunotangira pa50 kusvika 150 microns zvichienderana nevolti specifications.

Optical uye Reflective Layer Dhizaini

Reflective layers akatenderedza UV LEDs anofanirwa kushandisa zvinhu zvine yakakwira UV-spectrum reflectivity apo ichiratidza kuramba kushanduka. Silver-white reflective ingi dzakagadzirirwa zvakanangana neUV application dzinopa kuita kwakaringana. Sarudzo yekupedza pamusoro inofarira kunyudzwa sirivha kana electroless nickel kunyudzwa goridhe pamusoro pe organic solderability inochengetedza iyo inogona kuderera pasi pekuratidzwa kweUV.

Kuvimbika uye Upenyu Zvinhu

Kuvimbika kwenguva refu kunoenderana nekugadzikana kwezvinhu uye kudzora kushushikana kwekushisa. Zvese zvinoriumba zvinofanirwa kumira zvakadzokororwa kupisa bhasikoro pasina delamination kana solder kuneta. Dziviriro inogadzirisa machira inobatsira kudzivirira oxidation uye UV-induced degradation. Kushandisa RoHS-inoenderana, yakakwirira-tembiricha vatengesi inovandudza kutendeseka kwekubatana, nepo kuomarara-kutsva-mukati uye nekukurumidza kuchembera bvunzo kunosimbisa kuita kwekuita.

Nekugadzirisa kupisa kwekupisa, kuwirirana kwemagetsi, uye zvinhu zvinodzivirira UV, vagadziri vanogona kuwedzera zvakanyanya hupenyu hwekushanda hweUV LED magungano uye kuve nechokwadi chekubuda kwemaziso kwezviuru zvemaawa.
