Pcb bhodhi kufanotungamira kunotungamira kune ekugadzirisa matambudziko

1. Kune akawanda asinganzwisisike matambudziko muPCB maitiro, uye maitiro enjiniya anowanzo kutora mutoro we forensic autopsy (kuongororwa kwezvakaipa zvikonzero uye mhinduro). Naizvozvo, chinangwa chikuru chekutanga hurukuro iyi ndechekukurukura imwe neimwe munzvimbo yemidziyo, kusanganisira matambudziko anogona kukonzerwa nevanhu, michina, zvishandiso uye mamiriro. Ndinovimba iwe unokwanisa kutora chikamu mukati uye nekuisa pamberi pako wega maonero nemaonero

2. Kugona kushandisa mashandisirwo emidziyo yekufanobata mushonga, senge yemukati dhayeti yekudyira, electroplating mhangura yekunyepedzera tambo, D / F, anti welding (resistance welding)… Uye zvichingodaro

3. Tora pre-kurapwa mutsetse we anti anti welding (resistance welding) yePCB redunhu bhodhi semuenzaniso (akasiyana vagadziri): kukwesha nekukuya * 2 mapoka -> kushambidza kwemvura -> acid pickling -> kushambidza mvura -> kutonhora mhepo banga -> kuomesa chikamu -> solar disc inogamuchira -> kuburitsa uye kugamuchira

4. Kazhinji, brushes dzesimbi nemabhurashi mavhiri e # 600 uye # 800 anoshandiswa, zvinova zvinokanganisa hukasha hwebhodhi pamusoro, uyezve zvinokanganisa kubatirira pakati peingi neingi yemhangura. Pasi pekushandisa kwenguva refu, kana zvigadzirwa zvisina kuiswa zvakaenzana kuruboshwe uye kurudyi, zviri nyore kuburitsa imbwa mapfupa, izvo zvinotungamira mukuumbana kusingaenzanisike kwepamusoro pebhodhi, kunyangwe mutsetse deformation uye musiyano wemavara wakasiyana pakati penzvimbo yemhangura uye inki mushure mekudhinda, Naizvozvo, iro rese brashi mashandiro anodikanwa. Pamberi pebrashi kukuya mashandiro, iyo bhurashi mucherechedzo bvunzo ichaitwa (mvura yekutyora bvunzo ichawedzerwa kana paine D / F). Chiyero chebrashi mucherechedzo chakayerwa chingangoita 0.8 ~ 1.2mm, iyo inosiyana zvichienderana nezvigadzirwa zvakasiyana. Mushure mekunge brashe yagadziriswa, iwo mwero webrashi vhiri unogadziriswa, uye mafuta ekuzodza anowedzerwa nguva dzose. Kana mvura ikasabikwa panguva yekukuya kwebrashi, kana iko kumanikidza kwekupfapfaidza kudiki kuti kuumbe kona yakaita kunge fan, poda yemhangura iri nyore kuitika, Zvishoma poda yemhangura inokonzeresa micro dunhu diki (dense waya nzvimbo) kana isina kukodzera yakakwira voltage bvunzo panguva apedza chigadzirwa bvunzo

Rimwe dambudziko riri nyore mukufanirwa kurapwa ihwo oxidation yeplate pamusoro, inozotungamira kumabhuru pane iyo pamusoro peplate kana cavitation mushure meH / A

1. Nzvimbo yemvura yakasimba inochengetedza roller yekufanotangisa haina kunaka, kuitira kuti asidhi iunzwe muchikamu chekuwachisa mvura zvakanyanya. Kana huwandu hwematangi ekuwachisa mvura muchikamu chekumashure asina kukwana kana iyo jekiseni mvura isingakwani, iyo asidi yakasara iri pamusoro peplate ichakonzerwa

2. Hunhu hwemvura husina kutsarukana kana kusvibiswa muchikamu chekushambidza mvura kuchakonzeresa kunamatirana kwezvinhu zvekunze pamusoro penzvimbo yemhangura

3. Kana iyo yekuisa mvura roller yakaomeswa kana kuguta nemvura, haizokwanise kutora zvinobudirira mvura pane zvigadzirwa zvinogadzirirwa, zvinova zvinokonzeresa mvura yakasara yakawandisa pamusoro peplate uye mugomba, uye yakatevera mhepo banga haigone kuzadza basa rayo. Panguva ino, yakawanda yemhedzisiro inokonzeresa ichave iri pamucheto pegomba mukati mekuchema mamiriro

4. Kana kuchine tembiricha yakasara panguva yekudonhedza, ndiro yacho yakapetwa, inozoisa oxidize iyo yemhangura muplate.

Kazhinji kutaura, pH detector inogona kushandiswa kuongorora pH kukosha kwemvura, uye infrared ray inogona kushandiswa kuyera kuburitsa kunosara tembiricha yeplate pamusoro. A rezuva ndiro retractor yakaiswa pakati pekuyerera uye stack ndiro repuraketi kutonhodza ndiro. Iyo kunyorova kwemvura inonaya chinotenderera inoda kudomwa. Zvakanakisa kuve nemapoka maviri emavhiri ekupinza mvura kuti achenese neimwe nzira. Iyo kona yebanga remhepo inoda kusimbiswa kusati kwaitwa mashandiro ezuva nezuva, uye uteerere kana gomba remhepo muchikamu chekuomesa rinodonha kana kukuvara.
