Heat Capacity of Epoxy Molding Compound

What is the heat capac­i­ty of epoxy mold com­pounds used in semi­con­duc­tor assem­bly?

Though this infor­ma­tion varies based on many vari­ables, the most crit­i­cal para­me­ters are the filler load­ing and the load­ing per­cent­age. Since most epoxy mold com­pounds use sil­i­ca as filler and are on aver­age between 80–85% loaded, the approx­i­mate heat capac­i­ty for these mate­ri­als is 0.8J/gK.

  1. Hi! I am doing a study about epoxy mold­ing com­pound. I would like to ask the process on how to mix the epoxy resin, cat­a­lyst, sil­i­ca filler, hard­en­er, and addi­tives. Prefer­ably the detailed pro­ce­dure. Thank you.

  2. what is the exact appli­ca­tion of epoxy mold compound,which type of indus­tries use it,and what are the grades avail­able in the market.can you give us some ref no in India.

  3. Epoxy Mold Com­pound is used to encap­su­late & pro­tect semi­con­duc­tor devices and elec­tron­ic mod­ules. His­tor­i­cal­ly, ceram­ic pack­ages with sol­dered and glass-fired seams were used, but because of the high price of such pack­ages, now these are typ­i­cal­ly only reserved for med­ical, mil­i­tary or aero­space appli­ca­tions — appli­ca­tions where the cost-to-change due to reg­u­la­to­ry or cus­tomer spec­i­fi­ca­tions is very, very high com­pared to the cost of the mate­ri­als them­selves.

    More cost-sen­si­tive devices, such as con­sumer hand­helds, mobile phones, com­put­ers and any oth­er elec­tron­ic device now use epoxy to encap­su­late and pro­tect. Epoxy comes in sev­er­al forms, the most famil­iar being liq­uid, 2-part form. These epox­ies were also used exten­sive­ly while the device mix was high and vol­umes were rel­a­tive­ly low.

    Nowa­days, some man­u­fac­tur­ers and facil­i­ties make 20 — 40 bil­lion parts per year, and a liq­uid encap­su­la­tion sys­tem would be an enor­mous bot­tle neck. Epoxy Mold­ing Com­pounds are pre-mixed, b-staged epox­ies that are put into mold­ing machines and trans­fer-mold­ed over semi­con­duc­tors and oher devices. Even auto­mo­tive man­u­fac­tur­ers are imple­ment­ing epoxy mold com­pounds to encap­su­late engine con­trol units (ECU) and oth­er auto­mo­tive com­po­nents.

    Because the equip­ment required to mold devices is very expen­sive and has lim­it­ed flex­i­bil­i­ty com­pared to liq­uid-dis­pense sys­tems. The push to go from liq­uid epox­ies to mold com­pounds is only jus­ti­fied once the mix is low enough and the vol­ume is high enough to jus­ti­fy this invest­ment. All major semi­con­duc­tor com­pa­nies use this tech­nol­o­gy today.

  4. hi!i’m cur­rent­ly work­ing on my the­sis on semicon.i was just won­der­ing is it pos­si­ble make a epoxy mould­ing com­pound from digly­cidyl ether of bisphe­nol- A (DGEBA) with the addi­tion of MMT clay? what are the things need­ed for it to qual­i­fy and be called a mould­ing com­pound. i would be real­ly grate­ful for your reply. thank you!

  5. Kind­ly let me know how are major manu­fec­tur­ers of epoxy Mould­ing Com­pound in india? r u hav­ing any data about Epoxy com­pound Manu­fec­tur­ers to indi­an indus­try?

    i would be great­ful for your reply.

  6. CAPLINQ rep­re­sents SolE­poxy Epoxy Mold­ing Com­pounds, a major Epoxy Mold­ing Com­pound sup­pli­er of Coat­ing Pow­ders, and Indus­tri­al Mold­ing Com­pounds for Auto­mo­tive and Indus­tri­al Appli­ca­tions. Fur­ther­more, we have an exist­ing sup­ply chain already to India. Please send us a the detailed spec­i­fi­ca­tion you require and we can rec­om­mend a prod­uct for you and pro­vide a sam­ple.

  7. hel­lo. I’m a uni­ver­si­ty stu­dent in Korea. I would like to ask you about epoxy mold­ing com­pound. I have to find a method to reduce CTE and increase ther­mal con­duc­tiv­i­ty but I can’t find mate­ri­als in google or oth­er web­sites. I think that some ingre­di­ents are con­tor­lled in EMC. Please help me I real­ly need some advice.
