The Kukula mwachangu kwa mafakitale amafoni, zamagetsi, ndi zolumikizirana zidalimbikitsa kukula kosalekeza komanso kukula kwachangu. Pulogalamu ya PCB makampani.Anthu ali ndi zofunikira zambiri pa chiwerengero cha zigawo, kulemera, kulondola, zipangizo, mitundu, ndi kudalirika kwa zigawo.

Komabe, chifukwa cha mpikisano wowopsa wamsika, mtengo wa zida za board za PCB ukuchulukirachulukira, opanga akuchulukirachulukira pamsika ndi mitengo yotsika kuti apititse patsogolo kupikisana kwawo kwakukulu.Komabe, kuseri kwa mitengo yotsika kwambiriyi imapezeka pochepetsa mtengo wazinthu komanso kukonza ndalama zopangira.Zipangizo nthawi zambiri zimakhala ndi ming'alu (ming'alu), zokopa, ndi kulondola kwake, magwiridwe antchito ndi zina zambiri sizinafike pamlingo womwe umakhudza kwambiri kugulitsa ndi kudalirika kwazinthu.

Poyang'anizana ndi zosiyanasiyana matabwa PCB dera pa msika, pali njira ziwiri kusiyanitsa matabwa PCB dera.Njira yoyamba ndi yoweruza kuchokera ku maonekedwe, ndipo ina ndiyo kuweruza kuchokera ku zofunikira zamtundu wa bolodi la PCB lokha.

Njira zodziwira mtundu wa bolodi wadera la PCB:

• Siyanitsani khalidwe la bolodi la dera kuchokera ku maonekedwe

1. Standard malamulo kukula ndi makulidwe.

The makulidwe a bolodi dera ndi osiyana ndi wa muyezo dera bolodi.Makasitomala amatha kuyeza ndikuyang'ana makulidwe ndi mafotokozedwe azinthu zawo.

2. Kuwala ndi mtundu

Bwalo loyang'anira dera lakunja limakutidwa ndi inki, ndipo bolodi loyang'anira dera limatha kugwira ntchito yotchinga.Ngati mtundu wa bolodi siwowala ndipo pali inki yocheperako, bolodi lodziyimira palokha silili bwino.

3. Kuwonekera kwa weld

Gulu lozungulira lili ndi magawo ambiri.Ngati kuwotcherera sikuli bwino, zigawozo zimakhala zosavuta kugwa pa bolodi la dera, zomwe zidzakhudza kwambiri khalidwe la kuwotcherera kwa bolodi la dera.Ndikofunika kwambiri kuzindikira mosamala ndikukhala ndi mawonekedwe amphamvu.

• Ma board apamwamba a PCB ozungulira ayenera kukwaniritsa zofunika izi

1. Zigawozo zimafunika kuti zikhale zosavuta kugwiritsa ntchito pambuyo pa kukhazikitsa, kugwirizana kwa magetsi kuyenera kukwaniritsa zofunikira;

2. Mzere wa mzere, makulidwe a mzere, ndi mtunda wa mzere wa mzere umakwaniritsa zofunikira kuti mzere usatenthedwe, kusweka, ndi kufupikitsa;

3. Khungu lamkuwa silophweka kugwa pansi pa kutentha kwakukulu;

4. Pamwamba pa mkuwa sikophweka oxidize, ngati oxidizes, idzasweka posachedwa;

5. Palibe ma radiation owonjezera amagetsi;

6. Maonekedwewo si opunduka, kupewa mapindikidwe a nyumba ndi dislocation wa wononga mabowo pambuyo unsembe.Tsopano onse ndi makina oyika, malo a dzenje la bolodi la dera ndi zolakwika zowonongeka kwa dera ndi mapangidwe ake ayenera kukhala mkati mwazovomerezeka;

7. Kutentha kwakukulu, chinyezi chambiri, ndi kukana kwapadera kwa chilengedwe ziyeneranso kuganiziridwa;

8. Zomwe zimapangidwira pamtunda ziyenera kukwaniritsa zofunikira za unsembe;
