PCBA Thermal Pads Design Requirements

1. Dab tsi yog thermal ncoo

Lub npe hu ua thermal pads, hais txog hauv qab ntawm cov khoom siv nrog cov hlau sab ntawm cov cua sov dissipation solder pads, feem ntau kuj muaj lub zog me me, feem ntau yog los ntawm cov cua kub dissipation pads ntawm lub tshav kub dissipation qhov rau hauv av txheej.Txhawm rau kom muaj cua sov zoo dua, qee zaum yuav tsum tau tsim lub qhov dej dab dej rau hauv lub qhov (tsis yog lub qhov ntsaws), kom reflow soldering molten solder yuav ntws mus rau sab nraub qaum, tsim cov hlaws hlaws, yog li cuam tshuam rau cov ntawv luam tawm ntawm cov khoom siv. qhov saum npoo ntawm cov hlaws dai.

2. Cov kev cai tsim

(1) Txhawm rau txo qhov tshwm sim ntawm tin hlaws, lub qhov tuaj yeem tsim los rau txoj kab uas hla ntawm ≤ 0.30mm lossis ≥ 0.80mm qhov;resin plug qhov nto plating (POFV) tsim kuj siv tau.

(2) Tig tawm tag nrho cov dab dej kub ntawm cov khoom siv thib ob kom lees txais qhov muaj cov hlaws dai.

(3) Tsim cov txheej txheem thermal.Yog hais tias lub PCB board thickness < 2.4 hli, thiab tus naj npawb ntawm cov txheej hauv av txuas nrog lub qhov cub kub < plaub txheej, cov molten solder yuav ntws mus rau hauv lub dab dej kub thiab tsim cov tin hlaws phenomenon.Yog li ntawd, nws pom zoo tias yog tias muaj cov txheej txheem hauv av sib txuas nrog cov txheej txheem cua sov (muaj cov txheej txheem pcb dab dej txuas nrog rau qhov loj tooj liab nto ntau tshaj li rau txheej, feem ntau yuav tsis tsim cov tin hlaws phenomenon.

1. Ua-nyob rau hauv vuam fume filtration system, zoo filtration ntawm teeb meem gases, zoo nkauj tsos thiab ib puag ncig tiv thaiv, ntau nyob rau hauv txoj kab nrog kev siv high-end ib puag ncig.

2. Cov kev tswj xyuas muaj cov yam ntxwv ntawm kev sib koom ua ke siab, cov lus teb raws sij hawm, tsis tshua muaj nqi, kev saib xyuas yooj yim, thiab lwm yam.

3. Cov khoom siv hluav taws xob tshwj xeeb tsim, nrog kev tswj xyuas qhov kub thiab txias, tsis sib xws ntawm qhov kub thiab txias hauv cheeb tsam thermal, kev ua haujlwm siab ntawm thermal them nyiaj, kev siv hluav taws xob tsawg thiab lwm yam ntxwv.

4. zoo nkauj thiab muaj xim liab, daj thiab ntsuab tswb muaj nuj nqi ntawm qhov taw qhia tsim.

5. Kev cai-tsim khiav tsav lub cev muaj zog raws li cov yam ntxwv ntawm B-hom mesh siv, kom ntseeg tau tias tsis sib xws ceev thiab lub neej ntev.
