Echiche Isi nke HDI
HDI na-anọchite anya High Density Interconnector, nke bụ ụdị mmepụta PCB (teknụzụ), na-eji obere blind/eli site na teknụzụ iji nweta njupụta nkesa ahịrị dị elu. Ọ nwere ike iru obere nha, arụmọrụ dị elu na ọnụ ahịa dị ala. HDI PCB bụ ịchụso ndị na-emepụta ihe, na-etolite mgbe niile gaa na njupụta dị elu na nkenke. Ihe a na-akpọ "elu" abụghị naanị na ọ na-eme ka arụmọrụ igwe ka mma, kamakwa ọ na-ebelata nha igwe. Teknụzụ High Density Integration (HDI) nwere ike ime ka imewe ngwaahịa ikpeazụ dịkwuo obere, ebe ọ na-emezu ụkpụrụ dị elu nke arụmọrụ eletrọniki na arụmọrụ.
HDI PCB na-agụnyekarị ihe ndị na-eme ka a gwuo ihe n'ìhè site na laser na ihe ndị na-eme ka a gwuo ihe n'ìhè site na igwe. A na-enweta teknụzụ nke iduzi n'etiti akwa dị n'ime na nke dị n'èzí site na usoro dịka site na lie site na, blind via, stacked holes, staggered holes, cross blind/elied via, through holes, blind via ejuputa electroplating, fine waya space small na micro holes in the diski, wdg.
E nwere ọtụtụ ụdị HDI PCB: otu oyi akwa, abụọ oyi akwa, atọ oyi akwa, anọ na njikọ oyi akwa ọ bụla.
● Nhazi nke otu oyi akwa HDI: 1+N+1 (ịpịpịa ugboro abụọ, igwu laser otu ugboro).
● Nhazi nke HDI nke oyi akwa abụọ: 2+N+2 (ịpịpịa ugboro atọ, igwu laser ugboro abụọ).
● Nhazi nke HDI nke dị n'ime akwa atọ: 3+N+3 (ịpịpịa ugboro anọ, ịkụnye laser ugboro atọ).
● Nhazi nke HDI nke oyi akwa anọ: 4+N+4 (ịpịpịa ugboro ise, ịkụnye laser ugboro anọ).
Site na ihe owuwu ndị dị n'elu, a pụrụ ikwubi na igwu laser otu ugboro bụ HDI nke nwere oyi akwa 1, ugboro abụọ bụ HDI nke nwere oyi akwa 2, wdg. Njikọ oyi akwa ọ bụla nwere ike ịmalite igwu laser site na bọọdụ isi. N'ikwu ya n'ụzọ ọzọ, ihe a ga-egwu laser tupu ịpịa bụ HDI nke oyi akwa ọ bụla.
Echiche Nhazi nke HDI
1. Mgbe anyị hụrụ imewe nwere oghere n'akụkụ BGA nke PCB nwere ọtụtụ oyi akwa, mana n'ihi oke oghere, anyị ga-eji obere paadị BGA na obere oghere iji nweta ntinye zuru oke na bọọdụ, kedu ka anyị ga-esi mee ya? Ugbu a, anyị ga-achọ iwebata PCB HDI dị elu nke a na-akpọkarị na PCBs dị ka ndị a.
Ngwa ọrụ ịgbapụta ihe na-emetụta ọrụ ịgbapụta ihe nke PCB ọdịnala. Mgbe nha oghere ịgbapụta ihe ruru 0.15mm, ọnụ ahịa ya adịlarị oke elu ma ọ na-esiri ike imeziwanye ya. Agbanyeghị, n'ihi obere oghere, mgbe enwere ike ịnabata naanị nha oghere 0.1mm, echiche imewe nke HDI dị mkpa.
2. Ịgba HDI PCB anaghịzi adabere na ịgba ígwè nkịtị, kama ọ na-eji teknụzụ ịgba ígwè laser (mgbe ụfọdụ a makwaara ya dị ka bọọdụ laser). Ogo oghere ịgba ígwè nke HDI na-abụkarị 3-5mil (0.076-0.127mm), obosara ahịrị ahụ bụ 3-4mil (0.076-0.10mm), enwere ike ibelata nha nke ihe mkpuchi solder nke ukwuu, yabụ enwere ike nweta nkesa ahịrị karịa kwa mpaghara otu, na-ebute njikọ dị elu.
Mmalite nke teknụzụ HDI emeela ka ọ dabara ma kwalite mmepe nke ụlọ ọrụ PCB, na-eme ka e nwee ike ịhazi BGA, QFP, wdg karịa na HDI PCB. Ugbu a, ejirila teknụzụ HDI mee ihe nke ukwuu, nke ejirila HDI nke nwere otu oyi akwa mee ihe nke ukwuu na mmepụta PCB yana 0.5pitch BGA. Mmepe nke teknụzụ HDI na-akwalite mmepe nke teknụzụ chip, nke na-akwalite mmụba na ọganihu nke teknụzụ HDI.
Taa, ndị injinia nhazi ejirila nwayọọ nwayọọ na-eji ibe BGA nke nwere pitch 0.5, njikọ ndị na-agbakọta nke BGA agbanweela nwayọọ nwayọọ site na oghere etiti ma ọ bụ ụdị ala gaa na ụdị nwere ntinye na mmepụta mgbaàmà n'etiti nke chọrọ waya.
3. A na-ejikarị usoro nhazi eme ihe na-emepụta HDI PCB. Ka a na-eme nhazi ahụ ugboro ole na ole, otú ahụ ka ọkwa teknụzụ nke bọọdụ ahụ na-adị elu. A na-etinye PCB HDI nkịtị otu ugboro, ebe HDI dị elu na-eji teknụzụ nhazi ugboro abụọ ma ọ bụ karịa, yana teknụzụ PCB dị elu dịka nhazi oghere, ijupụta oghere site na iji electroplating na igwu laser ozugbo, wdg.
HDI PCB na-enyere aka iji teknụzụ mgbakọ dị elu, arụmọrụ eletriki na izi ezi nke akara dị elu karịa PCB ọdịnala. Na mgbakwunye. HDI nwere mmezi ka mma na nnyonye anya redio, nnyonye anya ebili mmiri electromagnetic, mwepụ electrostatic na conduction okpomọkụ, wdg.
