1. Chii chinonzi back drilling?

Kuchera kumashure imhando yakakosha yekuchera gomba rakadzika. Mukugadzirwa kwemapuranga emapuranga akawanda, akadai semapuranga gumi nemaviri, tinoda kubatanidza chikamu chekutanga kune chepfumbamwe. Kazhinji, tinochera kuburikidza negomba (chibhorani chimwe chete) uye tozonyura mhangura.Nenzira iyi, pasi rekutanga rakabatana zvakananga kune 12th floor. Kutaura zvazviri, isu tinongoda pasi pekutanga kuti tibatanidze kune 9th floor, uye 10th pasi kusvika ku12th floor nokuti hapana mutsara wekubatanidza, sembiru.Iyi mbiru inokanganisa nzira yechiratidzo uye inogona kukonzera matambudziko ekutendeseka kwechiratidzo mukati. Kukurukurirana zviratidzo.Saka chibooresa mbiru redundant (STUB muindasitiri) kubva reverse divi (chipiri chibooreso).Saka anonzi musana chibooreso, asi kazhinji kwete chibooreso chakachena, nokuti rinozotevera muitiro zvichaita electrolysis kure zvishoma mhangura, uye chibooreso muromo. pachayo inonongedza.Saka, mugadziri wePCB achasiya chidimbu chidiki. Hurefu hwe STUB hwe STUB iyi inodaidzwa kuti B kukosha, iyo inowanzova pakati pe50-150um.

2.The zvakanakira musana kuchera

1) kuderedza kupindira kweruzha

2) kunatsiridza kuvimbika kwechiratidzo

3) mukobvu ndiro ukobvu inoderera

4) kuderedza kushandiswa kwemakomba akavigwa mapofu uye kuderedza kuoma kwekugadzirwa kwePCB.

3. Kushandiswa kwekuchera kumashure

Kudzokera kudhiraivha kwaisave nekubatana kana mhedzisiro yegomba chikamu, dzivirira kukonzeresa kuratidzwa kweyepamusoro-kumhanya chiratidzo chekufambisa, kuparadzira, kunonoka, nezvimwewo, kunounza kune chiratidzo che "kukanganisa" tsvakiridzo yakaratidza kuti chikuru. zvinhu zvinopesvedzera chiratidzo chechiratidzo chekuvimbika dhizaini, dhizaini zvinhu, mukuwedzera kune zvinhu zvakaita semitsara yekufambisa, zvibatanidza, chip mapakeji, gomba rekutungamira rine mhedzisiro yakakura pakutendeseka kwechiratidzo.

4. Kushanda musimboti wekuchera kumashure

Kana tsono yedhiri ichidhiriwa, iyo diki yazvino inogadzirwa kana tsono yedhiri inobata foil yemhangura pamusoro peplate yepasi inosimudzira nzvimbo yehurefu hweplate, uye ipapo kudhirowa kunoitwa zvinoenderana neyakagadzika kudzika kudzika, uye chibooreso chichamiswa kana kudzika kwekuchera kwasvikwa.

5.Back drilling production process

1) ipa PCB ine gomba rekushandisa. Shandisa gomba rekushandisa kuisa PCB nekuboora gomba;

2) electroplating the PCB mushure mekuchera gomba, uye simbisa gomba nefirimu rakaoma pamberi pe electroplating;

3) gadzira yekunze layer giraidhi pane electroplated PCB;

4) kuitisa pateni electroplating paPCB mushure mekugadzira iyo yekunze pateni, uye kuitisa yakaoma firimu yekuisa chisimbiso chegomba rekuisa pamberi pemuenzaniso electroplating;

5) shandisa buri rekumisikidza rinoshandiswa nechibooreso chimwe kuti uise chibooreso chekumashure, uye shandisa chibooreso chekucheka kumashure chiboora buri re electroplating rinoda kudzoserwa kumashure;

6) geza kuchera kumashure mushure mekuchera kumashure kuti ubvise zvakasara zvekucheka mukuchera kumashure.

6. Unyanzvi hunoita hwemashure ekuchera ndiro

1) Rigid board (yakawanda)

2) Kazhinji i8 - 50 layers

3) Bhodhi ukobvu: pamusoro pe2.5mm

4) Hukobvu dhayamita yakakura

5) Saizi yebhodhi yakakura

6) Diminimum gomba dhayamita rekutanga drill is > = 0.3mm

7) Wekunze redunhu kushoma, yakawanda sikweya dhizaini yegomba rekumanikidza

8) Gomba rekumashure rinowanzova 0.2mm hombe pane buri rinoda kuboorwa

9) Kudzika kushivirira ndiko +/- 0.05mm

10) Kana chibooreso chekumashure chichida kudhiriwa kuM layer, ukobvu hwepakati pakati peM layer uye m-1 (inotevera layer yeM layer) huchave hushoma hwe0.17mm.

7.Kushandiswa kukuru kweplate yekuchera kumashure

Midziyo yekukurukurirana, server hombe, zvemagetsi zvekurapa, mauto, aerospace uye mamwe minda. Sezvo mauto neaerospace ari maindasitiri ane hunyanzvi, Iyo yekumashure yekumashure inowanzopihwa nesangano rekutsvagisa, tsvagiridzo nekusimudzira nzvimbo yemauto neaerospace masisitimu kana PCB vagadziri vane simba rakasimba remauto uye aerospace kumashure. indasitiri, uye ikozvino kutaurirana midziyo yekugadzira munda iri kukura zvishoma nezvishoma.
