Izinzuzo ze-aluminium substrate PCB

a. Ukukhipha ukushisa kungcono kakhulu kunesakhiwo esijwayelekile se-FR-4.

b. I-dielectric esetshenziswayo imvamisa izikhathi ezi-5 kuye kweziyi-10 ukuguquguquka okushisayo kwengilazi ye-epoxy yendabuko kanye no-1/10 ubukhulu.

c. Inkomba yokudlulisa ukushisa isebenza kangcono kune-PCB eqinile yendabuko.

d. Ungasebenzisa izisindo zethusi ezingaphansi kwalezo eziboniswe eshadini le-IPC elinconyiwe.

I-Aluminium PCB

Ukusetshenziswa kwe-aluminium substrate PCB

1. Imishini yomsindo: ama-amplifiers okokufaka nokukhiphayo, ama-amplifiers alinganiselayo, ama-audio amplifiers, ama-preamplifiers, izikhulisamandla, njll.

2. Imishini yokuhlinzeka ngogesi: isilawuli sokushintsha, isiguquli se-DC/AC, isilawuli se-SW, njll.

3. Imishini kagesi yokuxhumana: isikhulisi se-high-frequency umbiko wesifunda.

4. Imishini ezenzakalelayo yehhovisi: ama-motor drives, njll.

5. Izimoto: isilawuli sikagesi, isibasi, isilawuli samandla, njll.

6. Ikhompyutha: Ibhodi le-CPU `floppy disk drive’ iyunithi yokunikeza amandla, njll.

7. Imojula yamandla: inverter “solid state relay” rectifier bridge, njll.

Aluminium substrates asetshenziswa kabanzi. Ngokujwayelekile imishini yokulalelwayo, okokusebenza kagesi, kanye nemishini ye-elekthronikhi yokuxhumana, kukhona ama-PCB e-aluminium substrate, okokusebenza okuzenzakalelayo kwehhovisi, izimoto, amakhompyutha namamojula wamandla.

Kunomehluko emithathu phakathi kwebhodi le-fiberglass ne-aluminium substrate PCB

A. Intengo

Izingxenye ezibalulekile ze-LED fluorescent tube yilezi: ibhodi lesifunda, i-chip ye-LED kanye nokunikezwa kwamandla okushayela. Amabhodi wesifunda ajwayelekile ahlukaniswe abe izinhlobo ezimbili: ama-aluminium substrates namabhodi we-fiberglass. Ukuqhathanisa intengo yebhodi le-fiberglass ne-aluminium substrate, intengo ye-fiberglass board izoba ishibhile kakhulu, kodwa ukusebenza kwe-aluminium substrate kuzoba ngcono kunebhodi le-fiberglass.

B. Izici zobuchwepheshe

Ngokusho kwezinto ezihlukene kanye nezinqubo zokukhiqiza, amabhodi e-fiberglass angahlukaniswa abe izinhlobo ezintathu: amabhodi e-copper foil fiberglass anezinhlangothi ezimbili, amabhodi e-fiberglass ane-copper foil, kanye namabhodi e-fiberglass ye-copper foil enezinhlangothi ezimbili. Yiqiniso, intengo yamabhodi e-fiberglass eyenziwe ngezinto ezihlukahlukene izohluka. Izintengo zamaphaneli e-fiberglass enziwe ngezinto ezahlukahlukene kanye nobuchwepheshe nawo ahlukile. Umthelela wokuqeda ukushisa weshubhu le-LED le-fluorescent kanye nebhodi le-fiber yengilazi awumuhle njengalowo weshubhu le-LED le-fluorescent eliqukethe i-aluminium substrate.

C. Ukusebenza

Njengoba sonke sazi, i-aluminium substrate inokusebenza okuhle kokukhipha ukushisa, futhi ukusebenza kwayo kokukhipha ukushisa kungcono kakhulu kunebhodi le-fiberglass. Ngenxa yokuthi i-aluminium substrate ine-conductivity enhle yokushisa, i-aluminium substrate idlala indima ebalulekile emkhakheni wezibani ze-LED.
