Zvikamu zveakadhindwa redunhu bhodhi (PCB)

1. Layer

Yakadhindwa Circuit Board(PCB) layer inopatsanurwa kuita layer yemhangura uye isiri yemhangura layer, inowanzonzi mashoma mashoma ebhodhi kuratidza huwandu hwehuwandu hwemhangura layer.Kazhinji, welding pads uye mitsetse inoiswa pamhangura yemhangura kuti ipedze kubatana kwemagetsi.Isa chinyorwa chetsanangudzo hunhu kana hunhu hwekutaura pane isiri-copper coating;Mamwe mazinga (akadai sema mechanical layers) anoshandiswa kuisa ruzivo rwechiratidziro pamusoro pekugadzira bhodhi uye nzira yekubatanidza, senge yemuviri dimension line yebhodhi, dimension marking, data data, kuburikidza negomba ruzivo, mirairo yegungano, nezvimwe.

2.Via

Kuburikidza negomba chimwe chezvakakosha zvikamu zve multilayer PCB.Mutengo wekuchera gomba kazhinji 30% kusvika 40% yemutengo weakadhindwa redunhu board (PCB).Muchidimbu, gomba rega rega paPCB rinogona kunzi buri.Kubva pakuona kwekushanda, iyo kuburikidza-gomba inogona kugoverwa muzvikamu zviviri: imwe inoshandiswa sekubatanidza magetsi pakati pega yega yega;Yechipiri inoshandiswa kugadzirisa kana kutsvaga zvishandiso.Panyaya yemaitiro etekinoroji, maburi anowanzo kupatsanurwa muzvikamu zvitatu, kureva, bofu via.Kuvigwa kuburikidza uye kuburikidza.

3. Pad

Iyo padhi inoshandiswa pakushongedza zvinhu, kuona kubatanidzwa kwemagetsi, kugadzirisa mapini ezvikamu kana kudhirowa waya, mitsara yekuyedza, etc. Zvinoenderana nerudzi rwepakeji yezvikamu, iyo padhi inogona kukamurwa kuita mapoka maviri: tsono yekupinza pedhi uye pamusoro. chigamba pad.Iyo tsono yekupinza pedhi inofanirwa kudhiriwa, nepo pedhi yepasi haidi kuti iboorwe.Iyo welding plate yetsono-inopinza mhando yemhando yakaiswa mu-multi-layer, uye iyo welding plate yepasi SMT mhando yezvikamu inoiswa mune imwechete layer ine zvikamu.

4.Track

Copper film wire iwaya inomhanya paPCB mushure mecopper clad plate yagadziriswa.Inodanwa sewaya muchidimbu.Inowanzo shandiswa kuona kubatana pakati pemapadhi uye chikamu chakakosha cheakadhindwa redunhu bhodhi (PCB).Chinhu chikuru chetambo hupamhi hwayo, hunoenderana nehuwandu hwekutakura ikozvino uye hupamhi hwehuputi hwemhangura.

5. Chikamu Package

Component package inoreva welding iyo chaiyo chikamu kune yakadhindwa redunhu bhodhi (PCB) kutungamira mapini kunze.Ipapo iyo yakagadziriswa yekurongedza inova yakazara.Iwo akajairika encapsulation marudzi ndeye plug-in encapsulation uye pamusoro akaiswa encapsulation.
