Iyo metalized hafu-gomba inoreva kuti mushure mekuchera gomba (drill, gong groove), ipapo yechipiri yakaboorwa nekuumbwa, uye pakupedzisira hafu yegomba resimbi (groove) inochengetwa.Kuti adzore kugadzirwa kwesimbi hafu-gomba mapuranga, redunhu bhodhi vagadziri kazhinji kutora matanho nokuda muitiro matambudziko pamharadzano metallized hafu-makomba uye non-metallized makomba.


Metallized hafu-gomba maPCB ane mashoma ekushandisa mumaindasitiri akasiyana-siyana pane maPCB.Iyo metallized hafu-gomba iri nyore kuvhomora mhangura inonyura mugomba kana ichikuya, saka chiyero chezviraswa mufekitori yebhodhi redunhu chakanyanya kukwirira.


Chii a metallized hafu-gomba redunhu bhodhi ndizvo?

Metallized hafu-gomba redunhu bhodhi
Nzira yekugadzira yemhando iyi yebhodhi inogadziriswa maererano nemaitiro anotevera: kuchera (kuchera, gong groove-plate plating- --External light imaging--Pattern plating--Drying--Semi-hole processing--Kubvisa Firimu, etching, uye kubvisa tin--Mamwe maitiro--Shape


Iyo chaiyo metallized hafu-maburi inobatwa nenzira inotevera: ese metallized hafu-gomba PCB maburi anofanira kucherwa pateni mushure mekuputira, uye usati waiswa, chera gomba pamharadzano yemativi ese ehafu yegomba.

1) Dhipatimendi reinjiniya rinogadzira iyo MI maitiro zvinoenderana nemaitiro,
2) Iyo simbi hafu-gomba ndiyo yechipiri-yakaboorwa hafu-gomba yakaboorwa panguva yekutanga kuchera (kana gong), mushure mekunge chifananidzo chaputirwa, uye pamberi pe etching.Inofanirwa kutariswa kana mhangura ichaburitswa pachena kana gong groove yakaumbwa, uye iyo yakaboorwa hafu-gomba inofanira kutamirwa muyuniti.
3) Gomba rekurudyi (rakaboora hafu yegomba): a.Pedzisa kuchera kutanga, wozoshandura bhodhi pamusoro (kana girazi nzira);chera buri rekuruboshwe.b.Chinangwa ndechekuderedza kudhonzwa kwegomba remhangura muhafu yegomba nechibooreso, zvichikonzera kushaikwa kwegomba remhangura.
4) Saizi yemboro yekuboora hafu yegomba zvinoenderana nekuparadzaniswa kwemutsara wecontour.
5) Dhirowa solder mask firimu, shandisa gongo senzvimbo yekumira uye vhura hwindo kuti uwedzere kurapwa.
