PCB yakachena yakakosha pakuvimbika. Yakadhindwa redunhu bhodhi dzimwe nguva inogona kuunganidza huruva kana zvimwe zvinosvibisa uye inoda kucheneswa. PCB ine tsvina inogona kukanganisa basa rakakodzera rekugadzirwa kwayo. Kunyangwe bhodhi rako rakasviba nekuda kwekusangana nenzvimbo yaro yekushanda, kana nekuti kurongedza kwaro kana kudzivirira hakuna kuchengetedzwa zvakanaka, zvakakosha kuita nzira dzekuchenesa dzakakodzera kuti uvandudze kuvimbika.

Ko PCB yakasviba inokanganisa sei basa

Guruva rine zvinhu zvakaturikwa mumhepo. Iyo yakaoma muzvisikwa uye kazhinji ine musanganiswa weinorganic mineral materials, mvura-soluble salts, organic materials uye shoma shoma yemvura.

Sezvo zvikamu zveSMT zvichiva zviduku uye zvishoma, njodzi yekukundikana nekuda kwekusvibiswa inowedzera. Zvidzidzo zvakaratidza pachena kuti guruva rinoita kuti mapuranga edunhu anyanye kukanganiswa nekutadza kunoenderana nekunyorova, sekurasikirwa kwekudzivirira kwekudzivirira kwepamusoro, kutama kwemagetsi, uye ngura.

Nzira yekuchenesa PCB

Kuwedzera kutarisirwa kunofanira kutorwa pakuchenesa PCB. ESD precautions inofanirwa kutariswa uye inofanirwa kubviswa uye kuitwa munzvimbo yakaoma. Kana iwe ukashandisa zvisiri izvo nzira dzekuchenesa kana maitiro, bhodhi rinogona kusashanda zvachose.

Geza guruva

Kune guruva, nzira yakanakisisa yekubvisa guruva ndeyekuputira bhodhi redunhu rakachena nemhepo yakamanikidzwa. Ngwarira nzvimbo dzakaoma dzinogona kukonzera kukanganisa. Bhuroshi ndechimwe chishandiso chaunogona kushandisa kubvisa huruva.

Kuyerera kwakachena

Mabhodhi edunhu ane yasara flux AIDS anofanirwa kucheneswa nesaponifying agent. Kune vanodzidzira uye mainjiniya, zvinowanzoitika kupukuta waini. Bhuroshi remazino rinogona kunyoroveswa nedoro uye rinogona kushandiswa kukwesha chero kubuda. Ndapota cherechedza kuti kana bhodhi yako welds isina-wash flux, zvichange zvakaoma kubvisa uye yakasimba yekuchenesa inogona kudiwa.

Chenesa ngura

Shandisa pasoda kuchenesa kuonda kudiki kunokonzerwa nemabhatiri nezvimwe zvinhu. Inogona kushandiswa kubvisa tsvina pasina kukuvadza bhodhi. Soda yekubikisa inobata zvinyoro nyoro uye inobatsira kubvisa ngura kana zvisaririra zvaisaita nemidziyo yakapfava yakaita sebhurasho rine mvura yakadirwa. Inoitawo neutralize acidity yezvakasara.
