Ndeupi mutsauko pakati FR4 epoxy fiberglass board uye 3240 epoxy fiberglass board?

Iyo yepamba epoxy fiberglass board inowanzoita 3240, uye FR4 epoxy fiberglass board is generally imported insulation board. But both are very different things from physical properties or chemical properties. Let me introduce it to everyone briefly:

1, 3240 epoxy glass fiber board, general full name: 3240 epoxy phenolic fiberglass cloth laminate. Inoshandisa epoxy resin glue uye phenolic zvinhu seanorapa agent. Kupisa kunowanzova 155 degrees. Zvirinani machining performance. Inonyatsokodzerawo ma transformer uye mafuta emagetsi. Density kazhinji haipfuure chiyero chenyika: 1.9.

Nekudaro, vazhinji vagadziri vepamba vava kutora chikamu mumafiller, senge talcum poda, kuitira kuchengetedza mutengo mukugadzira maitiro. Density yavo yakawedzera zvinoshamisa. Iyo zvakare inoderedza zvakanyanya kushanda kwemagetsi. Inokodzera chete kune general insulation mapurojekiti.

2. FR4 epoxy glass fiber board. Epoxy glue is used. But it is not a curing agent with phenolic materials. Purely cured at high temperature. It is compared with plastic pure. The temperature is usually greater than 180 degrees. The machining performance is very strong. A colleague once joked that cutting with a cutting machine cuts sparks.

inoratidza kushanda kwayo kwekugadzirisa. Uye haizotsemuka kana delaminate kana yashandiswa. Kuita kwemagetsi kwakasimba zvikuru. Inokodzera mabhodhi emagetsi emagetsi uye copper clad laminates. Iyo yepasi zvinhu inogona zvakare kuve ese machira akanaka. Electronic fiber jira. Iyo inowanzo kuve density ye1.85. Inopesana nemakemikari ekuora.

3240 epoxy fiberglass board uye FR4 epoxy fiberglass board ndiwo maviri anonyanya kufarirwa epoxy fiberglass board ari pamusika. Munhu wese anoti FR4 iri nani pane 3240. Ndeupi musiyano pakati pavo?

Musiyano 1: FR4 ine yakanaka murazvo unodzora kuita.

FR4 chigadzirwa chakavandudzwa che3240 epoxy glass fiber board. Iyo murazvo unodzoreredza kuita kweFR4 epoxy girazi fiber bhodhi inosangana neiyo yenyika UL94V-0 yakajairwa. 3240 epoxy girazi fiber bhodhi haina murazvo unodzora zvivakwa.

Musiyano 2: Rinochinja ruvara.

Rudzi rweFR4 rwakanyanya, jade, uye ruvara rwe3240 epoxy fiberglass board iri kupenya zvishoma. Hazvina kutaridzika chaizvo. Mazhinji emavara haana kunyanya kufanana.

Difference three: FR4 has no radiation and is environmentally friendly.

3240 epoxy girazi fiber board ine halogen-ine, iyo isinganyanyi kushamwaridzana nenharaunda uye nemuviri wemunhu. Izvo zvakare hazvienderane negwara renyika reGreen Sustainable Development. Iyo FR4 epoxy girazi fiber board ingori kupesana.

Musiyano 4: FR4 ine yakanaka yekudzivirira kugadzikana.

FR4 has better dimensional stability than 3240, and during the pressing process, the thickness tolerance of FR4 is also much better than 3240, which is more suitable for processing.

Musiyano wechishanu: FR4 inogona kuzvidzimisa kubva pamoto.

FR4 inogona kudzimwa zvakasikwa kana paita moto.

musiyano wechitanhatu: kunyura kwemvura yakaderera.

Kunwa kwayo mvura (D-24/23, ukobvu hweplate 1.6mm): ≤19mg, iyo inopa rubatsiro rwakanaka pakushandiswa kwayo mumatota akanyorova nemimwe michina.

Nekuti FR-4 epoxy girazi faibha bhodhi ine kuita kwakanaka kwazvo, iko zvino yave kushandiswa sechinhu chekuisa insulating zvikamu mumaindasitiri emagetsi neemagetsi. Ehe, 3240 epoxy fiberglass board ichine imwe musika nekuda kwemutengo wayo mukana.
