1. PCB dunhu pfupi rinokonzerwa netini inomhanya

1. Tin inomhanya inokonzerwa nekusaitwa mushe mukutenderera kwemishonga yemafirimu.

2. Ndiro iyo yadzosera firimu yakasungirirwa pamwechete kukonzeresa tini kumhanya.

Chechipiri, pcb pfupi redunhu inokonzerwa isina kuchena etching

1. Hunhu hwekucheka potion paramende kutonga kunokanganisa zvakananga iyo etching mhando.

3. Inoonekwa pcb microshort redunhu

1. Micro-pfupi wedunhu inokonzerwa neMyra firimu kukanda pamushini wekuratidzira;

2, yekuratidzira ndiro pamagirazi anokwenya anokonzerwa nemutsara micro pfupi wedunhu.

Chechina, clip firimu PCB pfupi dunhu

1. Iyo anti-coating denderedzwa yakatetepa. Paunenge uchiputira, kupfeka kunodarika hukobvu hwefirimu, ichigadzira iyo firimu clip, kunyanya iyo diki tambo kusiyanisa, zviri nyore kuita kuti ipfupi dunhu reiyo clip firimu.

2. Kugovaniswa kusingaenzanisike kwemaplate maplate. Mukuita kwe graphic electroplating, kupfeka kwemitsara iri kwayo kwakapfuura pakukora kweiyo firimu nekuda kwesimba rakakura, zvichikonzera kutenderera kupfupi kunokonzerwa nekunamatira firimu.

Shanu, isingaoneki pcb microshort redunhu

Invisible micro-pfupi redunhu ndiro dambudziko rinonetsa kwazvo kukambani yedu kwenguva yakareba uye rave iri dambudziko rakaomarara kugadzirisa. Inenge makumi mashanu kubva muzana emabhodhi akapedzwa ane matambudziko muyedzo akadaro mashoma-mapfupi wedunhu matambudziko. Chikonzero chikuru ndechekuti kune tambo dzesimbi kana zvidimbu zvesimbi zvisingaonekwe neziso rakashama mumutsara.

Nhanhatu, yakatarwa pcb pfupi dunhu

Chikonzero chikuru ndechekuti mutsetse wefirimu wakakwenenzverwa kana paine marara anovharira pane yakaputirwa skrini ndiro, uye iyo yakafukidzwa anti-kupfeka yakatarwa nzvimbo yakafumurwa mhangura inotungamira kune pfupi dunhu.

Manomwe, muvare pcb pfupi redunhu

1.

2. Iyo irikukudziridzwa muchina nzira yekuburitsa ndiro yakanyanyobatikana kukonzeresa kudhumhana nekukwaya pakati peplate nendiro.

3. Zvikwenya zvinokonzerwa neplate isina kukodzera inotora panguva yeelectroplating, kushanda zvisirizvo panguva yekuisa splint, kushanda zvisirizvo panguva yekubata kweplate pamberi petsetse mutsara.
