Product Detail

Resin Plugging Maitiro

Tsanangudzo

Resin plugging process inoreva kushandiswa kweresin kuvhara makomba akavigwa mukati memukati, wobva wadzvanya, iyo inoshandiswa zvakanyanya muhigh-frequency board uye HDI board;yakakamurwa kuita yechinyakare skrini yekudhinda Resin Plugging uye vacuum resin plugging.Kazhinji, maitiro ekugadzirwa kwechigadzirwa ndeyechinyakare screen printing resin plug hole, inova zvakare inonyanyozivikanwa maitiro muindasitiri.

Process

Pre process — drilling resin gole — electroplating — resin plug hole — ceramic grinding plate — kuchera neburi — electroplating — post process

Electroplating zvinodiwa

Maererano nemhangura ukobvu zvinodiwa, electroplating.Mushure me electroplating, iyo resin plug gomba yakachekwa kuti isimbise concavity.

Vacuum Resin Plugging Maitiro

Tsanangudzo

Vacuum screen printing plug hole muchina chinhu chakakosha chePCB indasitiri, chakakodzera PCB bofu resin plug gomba, diki buri resin plug gomba, uye diki gobvu ndiro gobvu resin plug gomba.Kuti uone kuti hapana bubble mu resin plug gole kudhinda, michina inogadzirwa uye inogadzirwa ine yakakwira vacuum, uye iyo yakakwana vacuum kukosha kwevacuum iri pasi pe50pA.Panguva imwecheteyo, iyo vacuum system uye skrini yekudhinda muchina wakagadzirwa ne anti vibration uye yakakwirira simba muchimiro, kuitira kuti michina ishande zvakanyanya kugadzikana.

Musiyano

Maitiro ekuyerera kwevacuum plug hole iri padyo neiyo yechinyakare screen kudhinda.Musiyano ndewekuti chigadzirwa chiri muvacuum state mune plug hole yekugadzira maitiro, ayo anogona kunyatso kudzikisa yakaipa mhedzisiro senge mabubble.
