Electronic jak ni grau n-gun ja nna, n-gun n law wa ai hte maren, kam hpa mai ai, bungli galaw lu ai, asak galu lu na matu, katsi ai hpe atsawm sha shapraw kau lu na matu ahkyak nga ai. Ndai shara hta, n-gun ja ai nbung hpe hkangzing ai arung arai ni, grau nna Tungsten magri hte Molybdenum magri ni gaw, shanhte a n mai malap ai manu hpe madun dan nga ai. Hpaji rawng ai hku n-gun n rawng ai nhprang rai ni hte magri mang ni a akyu rawng ai atsam ni hpe kayau kaya hpawng de ai hku nna, ndai nhprang rai ni gaw hpang na-prat na heat sink material hparan ladat ni a matu lata la mai ai arung arai ni tai wa sai.
1. Core Properties: Kaja dik htum a npawt nhpang
Tungsten Magri hte Molybdenum Magri n-gang ni gaw powder n-gang htu shapraw ai n-gun dat ni rai nga ai. Dai ni gaw asan sha kayau kaya ai n re ai sha, n-gun ja ai tungsten (sh) molybdenum n-gup magap hpe n-gun ja ai magri hte hpring hkra galaw ai infiltration sintering zawn re ai grai sawng ai ladat ni hku nna galaw shapraw ai re. Ndai lam gaw laklai ai tailorable properties ni hpe shabyin ya ai:
- Hkamja lam hpe hkang lu ai nbung n-gun jat wa ai lam: N-gun jat wa ai lam (CTE) hpe n-gun jat ai lam hpe hkrak hkrak galaw lu ai. Ga shadawn, 85%W-15%Cu lawm ai Tungsten magri mang n-gang gaw 6.5 ppm/℃daram sha CTE hpe lu la mai ai, dai gaw Alumina zawn re ai ceramics (sh) GaAs zawn re ai semiconductor arung arai ni hte ni htep ai hku htuk manu hkra galaw lu ai. Ndai lam gaw thermal stress hpe shayawm kau ya nna, ahkyak ai bonded interface ni hta hkrat sum ai lam hpe pat shingdang ya ai.
- High Thermal Conductivity: Composite kata na matut manoi nga ai magri mang daw gaw, nbung hpe htawt sit lu na matu kaja dik ai lam hpe jaw ya ai. Kalang lang nbung n-gun 160 kaw nna 240 W/(m·K du hkra rai nna, nbung n-gun hpe n-gun ja ai shara ni kaw nna tsan ai de lawan ai hku chyam bra wa shangun ai.
- Laksan Hkrang N-gun: Magri law ai raitim, n-gun n rawng ai magri n-gun gaw, nbung katsi ai aten hta mau hpa n-gun hte ngang kang ai lam hpe jaw ya nna, san seng ai magri hpe grau nna n-gun ja shangun ai. Ndai gaw thermal cycling npu hta dimensional hpe ngang grin hkra galaw ya ai.
- Lahta na chart hta ndai alloy ni a madung hkum hkrang atsam ni hpe san seng ai magri hte shingdaw nna, shanhte a grau kaja ai galai shai lu ai atsam hpe madi madun da ai:
2. Arung arai Grade hte Form ni: Laika shawk shawn ra ai lam amyu myu hpe hkap la ai
Ndai alloys ni hpe laksan thermal hte mechanical ra kadawn ai lam ni hpe hkan sa lu na matu, n bung ai n-gun dat ni hpe lang mai ai.
- Masha law malawng lang ai Tungsten magri mang n-gun: W70Cu30, W80Cu20, W85Cu15, W90Cu10. Tungsten law ai gaw ngang kang ai lam hpe jat ya nna CTE hpe shayawm ya ai, copper law ai gaw thermal conductivity hpe jat ya ai.
- Molybdenum magri n-gang ni hpe lang ai: Mo60Cu40, Mo70Cu30, Mo80Cu20, Mo85Cu15 ni hpe lang ai. Molybdenum copper gaw, madung hku nna, jai lang ai lam law law a matu, jak rung galaw lu ai atsam hte bungli galaw lu ai atsam hpe grau kaja ai hku rap ra hkra galaw ya lu ai.
- Thermal system ni hta hpaw shalawm na matu, ndai arung arai ni hpe hkrak tup ai hkrang ni hku nna jaw ai:
- Tungsten Magri Hpun/Plate: N-gun hpe hkrak shabra ai (sh) n-gun hpe n-gun dat ai hku lang ai. Shanhte hpe module layout langai ngai hte hkrak hkra, custom hkrang ni hku nna machine hte galaw chye ai.
- Flanges hte Submounts: Laser diode packages hte RF power amplifier ni hta ahkyak ai arung arai ni rai nna, nbung hpe hkang lu ai hte npawt nhpang hpe madi shadaw ya ai.
- Custom Machined Parts: Hkrak ai electronic hpawng ni a matu galaw da ai, nbung n-gun shayawm ai npawt nhpang, htaw ai plate, lead frame ni lawm ai.
3. Madung jai lang na shara ni
W-Cu hte Mo-Cu alloys ni a laklai ai atsam matrix gaw, grau ra kadawn ai nbung laru makau grup yin ni a matu kaja dik htum byin shangun ai:
