Yakakwana interlayer insulation kuita kweakawanda-layer PCB

Mune ino blog post, isu tichaongorora akasiyana matekiniki uye marongero ekuti tiwane yakakwana yekuisa insulation kuita mukatimulti-layer PCBs.

Multilayer PCBs anoshandiswa zvakanyanya mumhando dzakasiyana siyana dzemagetsi nekuda kwehukuru hwadzo uye compact dhizaini. Nekudaro, chinhu chakakosha chekugadzira uye kugadzira aya akaomarara edunhu mabhodhi kuve nechokwadi chekuti interlayer insulation zvivakwa zvinosangana nezvinodiwa.

Insulation yakakosha mumultilayer PCBs sezvo ichidzivirira kukanganiswa kwechiratidzo uye inova nechokwadi chekushanda kwakanaka kwedunhu. Kushongedzerwa kwakashata pakati pematanho kunogona kutungamira kune kusaina kuvuza, crosstalk, uye pakupedzisira kutadza kwemagetsi mudziyo. Naizvozvo, zvakakosha kufunga uye kuita zvinotevera matanho panguva yekugadzira uye kugadzira maitiro:

1. Sarudza chinhu chakakodzera:

Sarudzo yezvinhu zvinoshandiswa mune multilayer PCB chimiro inokanganisa zvakanyanya yayo interlayer insulation zvimiro. Insulating zvinhu senge prepreg uye core zvinhu zvinofanirwa kunge zvine yakakwira breakdown voltage, yakaderera dielectric inogara uye yakaderera dissipation chinhu. Pamusoro pezvo, kutarisisa zvinhu zvine hunyoro hwekudzivirira uye kugadzikana kwekupisa kwakakosha kuchengetedza zvivakwa zvekuisa mukati menguva refu.

2. Controllable impedance dhizaini:

Kudzora kwakaringana kwemazinga e impedance mu multilayer PCB dhizaini kwakakosha kuti uve nechokwadi chekuvimbika kwechiratidzo uye kudzivirira kukanganiswa kwechiratidzo. Nekunyatso verenga hupamhi hwekutsvagira nzvimbo, nzvimbo, uye kukora kwemutsetse, njodzi yekudonha kwechiratidzo nekuda kwekuisa zvisina kunaka inogona kuderedzwa zvakanyanya. Wana kwakaringana uye kunoenderana impedance kukosha neiyo impedance Calculator uye dhizaini mitemo inopihwa nePCB yekugadzira software.

3. Ukobvu hwekudzivirira hunokwana:

Ukobvu hweiyo insulation layer pakati pematanho emhangura ari padhuze inoita basa rakakosha mukudzivirira kuvuza nekusimudzira kuita kwese kuvharisa. Madhizaini edhizaini anokurudzira kuchengetedza kushoma insulation ukobvu kudzivirira kuparara kwemagetsi. Izvo zvakakosha kuyera ukobvu kuti usangane nezvinodiwa zvekuisa pasina kukanganisa kukora kwese uye kuchinjika kwePCB.

4. Kurongeka kwakakodzera uye kunyoresa:

Munguva yelamination, kurongeka kwakaringana uye kunyoreswa pakati pepakati uye prepreg layers inofanirwa kuve nechokwadi. Misalignment kana zvikanganiso zvekunyoresa zvinogona kukonzeresa kusaenzana kwemhepo migero kana ukobvu hwekuisa, zvichizokanganisa kuita kwe interlayer insulation. Kushandisa epamberi otomatiki optical alignment masisitimu anogona zvakanyanya kunatsiridza iko kurongeka uye kuenderana kwemaitiro ako ekugadzirisa.

5. Inodzorwa lamination maitiro:

Iyo lamination process inhanho yakakosha mukugadzirwa kwePCB yakawanda-layer, iyo inobata zvakananga iyo interlayer insulation performance. Yakasimba maitiro ekudzora ma paramita akadai sekumanikidza, tembiricha uye nguva inofanirwa kuitwa kuti iwane yunifomu uye yakavimbika insulation mukati mezvikamu. Kugara kutariswa uye kuoneswa kweiyo lamination process inovimbisa kuenderana kwemhando ye insulation mukati mekuita kwekugadzira.

6. Kuongorora uye kuongorora:

Kuve nechokwadi chekuti interlayer insulation performance ye-multi-layer PCB inosangana nezvinodiwa, kuongorora kwakasimba uye maitiro ekuyedza anofanirwa kuitwa. Kuita kwekudzivirira kunowanzo kuongororwa uchishandisa yakakwira voltage kuyedzwa, kuyerwa kwekudzivirira kwekudzivirira, uye kuyedza kutenderera kutenderera. Chero mabhodhi akaremara kana akaturikidzana anofanirwa kucherechedzwa uye kugadziriswa asati aenderera mberi nekugadzirisa kana kutumira.

Nekutarisa pazvinhu izvi zvakakosha, vagadziri uye vagadziri vanogona kuve nechokwadi chekuti interlayer insulation performance ye multilayer PCB inosangana nezvinodiwa. Kuisa nguva nezviwanikwa mukusarudza kwakakodzera kwezvinhu, dhizaini inodzorwa, dhizaini yakaringana, kurongeka kwakaringana, kudzora lamination, uye kuomarara kuyedzwa kunozokonzera yakavimbika, yepamusoro-inoshanda multilayer PCB.

Muchidimbu

Kuwana optimal interlayer insulation performance kwakakosha pakushanda kwakavimbika kwemultilayer PCB mumidziyo yemagetsi. Kuita matekiniki uye matinji anokurukurwa panguva yekugadzira uye kugadzira maitiro kuchabatsira kuderedza chiratidzo chekuvhiringidza, crosstalk, uye zvinogona kutadza. Rangarira, kufurira kwakaringana ndiyo hwaro hwekugadzira, yakasimba PCB dhizaini.
