Ukobvu hwemhangura uye kufa-kukanda maitiro e4L PCB

Maitiro ekusarudza akakodzera mu-bhodhi ukobvu hwemhangura uye mhangura foil kufa-kukanda maitiro e4-layer PCB

Paunenge uchigadzira uye kugadzira akadhindwa edunhu mabhodhi (PCBs), pane zvinhu zvakawanda zvekufunga nezvazvo. Chinhu chakakosha kusarudza yakakodzera mu-bhodhi ukobvu hwemhangura uye mhangura foil die-casting process, kunyanya kana uchibata ne4-layer PCBs. Mune ino blog post, tichakurukura kuti sei sarudzo idzi dzakakosha uye kukupa mamwe matipi ekuita sarudzo yakanaka.

Kukosha kwemhangura yemhangura mubhodhi

A PCB's in-board copper ukobvu inoita basa rakakosha mukuita kwayo kwese uye kuvimbika. Iyo inokanganisa zvakananga kugona kwebhodhi kuita zvakanaka magetsi uye kugadzirisa kupisa kupisa. Kusarudza iko kukora kwemhangura kwakakosha pakuona kuti PCB inokwanisa kubata inodiwa ikozvino pasina kupisa kwakanyanya kana madonhwe emagetsi.

Kana 4-layer PCBs inobatanidzwa, mamiriro acho anova akaomarara. Mamwe maturu muPCB anowedzera dhizaini yakaoma, uye ukobvu hwemhangura hunoda kunyatsotariswa kuchengetedza kuita kwakaringana. Asi zvinofanirwa kuyeukwa kuti ukobvu hunofanirwa kusarudzwa zvinoenderana nezvinodiwa zvePCB pane kungotevera neupofu chero maindasitiri akataurwa.

Zvinhu Zvokufunga nezvazvo Pakusarudza In-Board Copper Kukora

1. Kutakura kwazvino:Imwe yezvinonyanya kutariswa pakusarudza ukobvu hwemhangura ndeye ikozvino kutakura kugona kweiyo trace. Madhizaini edunhu ane masimba epamusoro-soro kana maapplication anoda kushanda kwepamusoro-ikozvino anofanirwa kushandisa mitsetse yemhangura yakakora kudzivirira kupisa kwakanyanya.

2. Kutarisira kupisa:Kushanda kupisa kupisa kwakakosha kuhupenyu hwePCB uye kuvimbika. Makumbo emhangura akaturikidzana anobatsira kuwedzera kupisa kupisa nekupa nzvimbo yakakura yepasi yekutamisa kupisa. Naizvozvo, kana chikumbiro chako chinosanganisira zvikamu zvinoburitsa kupisa kwakawanda, zvinokurudzirwa kusarudza dhaka rakakora remhangura.

3. Impedance control:Kune mamwe maapplication, akadai seyakakwira frequency kana redhiyo frequency maseketi, kuchengetedza chaiyo impedance kwakakosha. Muchiitiko ichi, iyo mu-bhodhi mhangura ukobvu inofanira kunyatsosarudzwa kuchengetedza inodiwa impedance kukosha. Makobvu emhangura akaturikidzana anobatsira kuwana chaiyo impedance control.

Kusarudza iyo chaiyo yemhangura foil die-casting process

Pamusoro pehukobvu hwemhangura, iyo copper foil die casting process ndechimwe chinhu chakakosha kufunga. Iyo die-casting process inosarudza kunaka uye kufanana kwemhangura layer paPCB. Heano zvimwe zvinhu zvekuchengeta mupfungwa pakusarudza nzira yekukanda kufa kwayo:

1. Kupera kwepamusoro:Iyo die-casting process inofanirwa kuve yakatsetseka uye yakafanana pamusoro pekupedzisira. Izvi zvakakosha kuve nechokwadi chekutengesa kwakanaka uye yakavimbika magetsi ekubatanidza. Kupera kwakashata kwepamusoro kunogona kukonzera matambudziko senge solder joint kutadza kana kusakwana conductivity.

2. Kunamatira:Iyo mhangura yemhangura inofanirwa kusungirirwa zvakasimba kuPCB substrate kudzivirira delamination kana kudonha panguva yekushanda. Iyo inofa-yekukanda maitiro inofanirwa kuve nechokwadi chekunamatira kwakanaka pakati pemhangura uye substrate zvinhu (kazhinji FR-4) kuve nechokwadi chekuvimbika uye hupenyu hurefu hwePCB.

3. Kuenderana:Kuenderana kwehukobvu hwemhangura mukati mePCB yese kwakakosha kuti uve nechokwadi chekuenderana kushanda kwemagetsi uye impedance control. Iyo yekukanda kufa inofanirwa kupa mhedzisiro inowirirana uye kuderedza misiyano mukukora kwemhangura.

Wana mwero wakafanira

Kurova chiyero chakakodzera pakati pekuita, kuvimbika uye mutengo kwakakosha pakusarudza yakakodzera mu-bhodhi ukobvu hwemhangura uye copper foil die-casting process. Makobvu emhangura akaturikidzana uye yakawedzera kufa-yekukanda maitiro anogona kuvandudza mashandiro, asi zvakare kuwedzera mutengo wekugadzira. Zvinokurudzirwa kubvunza ane ruzivo rwePCB mugadziri kana nyanzvi kuti uone iyo yakakwana yemhangura ukobvu uye kufa-kukanda maitiro ayo anozonyatsoenderana nezvako chaizvo zvaunoda uye zvipingaidzo zvebhajeti.

mukupedzisa

Kusarudza iyo chaiyo mu-bhodhi ukobvu hwemhangura uye mhangura foil kufa-casting maitiro kwakakosha pakuona kwenguva yakareba kuita, kuvimbika uye kushanda kwe4-layer PCB. Kunyatsofunga nezvezvinhu zvakaita seyazvino kutakura kugona, kudziya kwekutonga, uye impedance control yakakosha pakuita sarudzo chaiyo. Pamusoro pezvo, kusarudza nzira yekufa-yekukanda iyo inopa kupera kwakatsetseka kwepamusoro, kunamatira kwakanaka, uye mhedzisiro inowirirana inovandudza huwandu hwese hwePCB. Rangarira, dhizaini yega yega PCB yakasarudzika uye kuwana chiyero chakakwana pakati pezvinodiwa zvehunyanzvi uye kugona kwekugadzira ndiyo kiyi yekubudirira.
