PCB, sunan kasar Sin an buga kwamiti mai kewaya, wanda aka fi sani da sunan kewaya, yana da mahimman kayan haɗin lantarki, tallafi ne na kayan aikin lantarki, kayan haɗin lantarki shine mai ɗaukar haɗin lantarki. Next, Yong Ming Sheng masana'antar keɓaɓɓiyar pcb na alumini bayani game da aluminum substrate PCB zafin jiki Yunƙurin.

Tasirin tashin yanayin zafin jiki na hukumar kewaye

Dalilin kai tsaye na hauhawar zafin jiki na PCB akan matakan aluminum shine kasancewar na'urorin amfani da wuta a cikin da'irar. Amfani da wutar lantarki na na'urorin lantarki ya banbanta zuwa digiri daban-daban, kuma ƙarfin dumama ya bambanta da yawan amfani da wutar.

Abubuwa biyu na zafin jiki a cikin allon bugawa:

(1) haɓakar zafin jiki na gida ko haɓakar yanayin yanki mai girma;

(2) Hawan zafi na gajere ko na dogon lokaci.

Kullum, ana amfani da tasirin wutar lantarki mai amfani da PCB daga fannoni masu zuwa ：

1.Electrical power consumpti

(1) Yi nazarin amfani da wutar lantarki ta kowane yanki;

(2) Yi nazarin rarraba wuta akan hukumar PCB.

2. Tsarin tsarin hukumar kewaye

(1) Girman allon zagaye;

(2) Buga kewaye hukumar kayan.

3.Printed kewaye kwamitin shigarwa hanya

(1) Yanayin shigarwa (kamar shigarwa a tsaye, shigarwa a kwance);

(2) yanayin hatimi da nisa daga casing.

4.wanin zafi

(1) girka gidan ruwa;

(2) gudanar da sauran sassan tsarin shigarwa.

5. ƙarin radiation

(1) radiation coefficient na buga kewaye hukumar surface;

(2) bambancin yanayin zafin jiki tsakanin katangar kewaye da kewaye da yanayin zafinsu;

6.wankewar zafi

(1) isar da yanayi;

(2) Tilasta sanyaya convection.

Binciken abubuwa daban-daban hanya ce mai tasiri don magance haɓakar zafin jiki na allon bugawa, sau da yawa a cikin samfuri da tsarin waɗannan abubuwan suna da alaƙa da dogaro, yawancin abubuwan yakamata a bincika su ta hanyar ainihin yanayin, kawai don takamaiman ainihin halin da ake ciki na iya lissafin daidai ko kimanta haɓakar zafin jiki da amfani da ƙarfi da sauran sigogi.

Abubuwan da ke sama an tsara su kuma an buga su ta hanyar mai samar da kayan aikin aluminum. Idan ba ku fahimta ba, da fatan za a tuntube mu a " ymspcb.com ".
