Ubwino wa gawo lapansi la aluminiyamu PCB

a. Kutentha kwapang’onopang’ono ndikwabwinoko kuposa mawonekedwe a FR-4.

b. Dielectric yomwe imagwiritsidwa ntchito nthawi zambiri imakhala 5 mpaka 10 kuwirikiza kwa matenthedwe agalasi lakale la epoxy ndi 1/10 makulidwe.

c. Mlozera wotengera kutentha ndiwothandiza kwambiri kuposa PCB yokhazikika.

d. Mutha kugwiritsa ntchito zolemera zamkuwa zotsika kuposa zomwe zikuwonetsedwa mu tchati chovomerezeka cha IPC.

Aluminium PCB

Kugwiritsa ntchito aluminium gawo lapansi PCB

1. Zida zomvera: zowonjezera ndi zotulutsa zotulutsa, zowonjezera zomveka bwino, zowonjezera zomvetsera, zowonetseratu, zowonjezera mphamvu, ndi zina zotero.

2. Zida zopangira magetsi: kusintha kwa kusintha, DC / AC converter, SW regulator, etc.

3. Zipangizo zamagetsi zamagetsi: amplifier apamwamba kwambiri lipoti dera.

4. Zida zopangira ma Office: zoyendetsa galimoto, etc.

5. Magalimoto: chowongolera zamagetsi, choyatsira, chowongolera mphamvu, etc.

6. Makompyuta: CPU board `floppy disk drive’ mphamvu yamagetsi, ndi zina.

7. Power module: inverter “solid state relay” rectifier mlatho, etc.

Magawo a aluminiyamu amagwiritsidwa ntchito kwambiri. Mwambiri zida zomvera, zida zamagetsi, ndi zida zamagetsi zolumikizirana, pali ma PCB a aluminiyamu, zida zamagetsi zamagetsi, magalimoto, makompyuta ndi magawo amagetsi.

Pali kusiyana katatu pakati pa bolodi la fiberglass ndi aluminium substrate PCB

A. Mtengo

Zofunikira za chubu cha fulorosenti ya LED ndi: board board, chip cha LED ndi magetsi oyendetsa. Ma board ozungulira wamba amagawidwa m’mitundu iwiri: magawo a aluminiyamu ndi matabwa a fiberglass. Poyerekeza mtengo wa fiberglass board ndi aluminiyamu gawo lapansi, mtengo wa fiberglass board udzakhala wotsika mtengo kwambiri, koma magwiridwe antchito a aluminium gawo lapansi adzakhala abwino kuposa a board fiberglass.

B. Mbali zaukadaulo

Malinga ndi zida zosiyanasiyana komanso njira zopangira, matabwa a fiberglass amatha kugawidwa m’mitundu itatu: matabwa amitundu iwiri amkuwa, ma board a fiberglass opangidwa ndi mkuwa, ndi matabwa amkuwa amkuwa amkuwa. Zoonadi, mtengo wamatabwa a fiberglass opangidwa ndi zinthu zosiyanasiyana udzakhala wosiyana. Mitengo ya mapanelo a fiberglass opangidwa ndi zinthu zosiyanasiyana komanso matekinoloje amasiyananso. Kutentha kwapang’onopang’ono kwa chubu cha fulorosenti ya LED ndi bolodi lagalasi sikwabwino ngati chubu la fulorosenti la LED lomwe lili ndi gawo lapansi la aluminiyamu.

C. Magwiridwe

Monga tonse tikudziwira, gawo lapansi la aluminiyamu lili ndi ntchito yabwino yochepetsera kutentha, ndipo ntchito yake yochotsa kutentha ndi yabwino kwambiri kuposa bolodi la fiberglass. Chifukwa gawo lapansi la aluminiyamu lili ndi matenthedwe abwino, gawo lapansi la aluminiyamu limagwira ntchito yofunika kwambiri pagawo la nyali za LED.
