What are the functions of FR4 epoxy board?
Mesebetsi ea FR4 epoxy board?
1. Various forms:
Li-resin tse fapaneng, liakhente tse phekolang, le litsamaiso tsa ho fetola li ka batla li ikamahanya le litlhoko tsa lits’ebetso tse fapaneng foromong, ‘me mefuta e ka ba ho tloha ho viscosity e tlase haholo ho isa ho lintho tse tiileng tse qhibilihang.
2. Convenient curing:
Khetha mefuta e fapaneng ea mefuta e fapaneng ea pheko, sistimi ea epoxy resin e ka batla e phekoleha maemong a mocheso a 0 ~ 180 ℃.
3. Low shrinkage:
Boitšoaro lipakeng tsa resin ea epoxy le sesebelisoa se phekolang se sebelisitsoeng se etsoa ka karabelo e tobileng ea tlatsetso kapa karabelo ea ho bula li-polymerization ea lihlopha tsa epoxy ka har’a molek’hule ea resin, ‘me ha ho na metsi kapa lihlahisoa tse ling tse senyehang. Ha li bapisoa le li-resin tsa polyester tse sa tsitsang le li-phenolic resin, li bontša ho fokotseha haholo (ka tlase ho 2%) nakong ea ho phekola.
4. Strong adhesion:
Lihlopheng tsa tlhaho tsa polar hydroxyl le li-bond tsa ether ka har’a ketane ea molek’hule ea li-epoxy resin li etsa hore e khomarele haholo linthong tse fapaneng. The shrinkage ea epoxy resin e tlaase ha e phekoloa, ‘me khatello ea ka hare e hlahisoang e nyenyane, e thusang ho ntlafatsa matla a ho khomarela.
5. Mechini ea mechini:
Sistimi ea epoxy resin e phekotsoeng e na le thepa e ntle haholo ea mochini.
