Tinowanzo bvunzwa nezvekuchinjika. Ehe, sei zvimwe ungade bhodhi re "flex"?
"Ko bhodhi rinochinjika richatsemuka here kana rikashandisa mhangura yeED pariri?"
Muchinyorwa chino tinoda kuongorora zvinhu zviviri zvakasiyana (ED-Electrodeposited uye RA-rolled-annealed) uye kuona kukosha kwazvo pakugara kwenguva refu kwedunhu. Kunyangwe zvichinzwisiswa zvakanaka neindasitiri yeflex, hatisi kuwana shoko rakakosha kumugadziri webhodhi.
Ngatitorei nguva yekuongorora mhando mbiri idzi dzefoil. Heino ongororo yeRA Copper neED Copper:
Kuchinjika kwemhangura kunobva pazvinhu zvakawanda. Ehe, iyo yakatetepa ndiyo mhangura, bhodhi rinochinjika zvakanyanya. Pamusoro pekukora (kana kutetepa), tsanga yemhangura inokanganisawo kuchinjika. Kune mhando mbiri dzemhangura dzinoshandiswa mumisika yePCB neflex circuit: ED neRA sezvambotaurwa.
Roll Anneal Copper Foil (RA copper)
Mhangura yeRolling Annealed (RA) yave ichishandiswa zvakanyanya mukugadzira macircuits anochinjika uye muindasitiri yekugadzira maPCB anochinjika-chinjika kwemakumi emakore.
Maumbirwo egorosi nepamusoro paro pakanyatsotsetseka zvakanaka pakushandiswa kwemagetsi anochinjika uye anochinjika. Imwe nzvimbo inonakidza ine mhando dzemhangura dzakamonerwa inowanikwa mumasaini emagetsi anotenderera zvakanyanya.
Zvave zvichiratidzwa kuti kuomarara kwemusoro wemhangura kunogona kukanganisa kurasikirwa kwekupinza kwepamusoro-soro uye kuti musoro wemhangura wakatsetseka unobatsira.
Kuisa Electrolysis Copper Foil (ED copper)
Nemhangura yeED, kune mhando dzakasiyana-siyana dzemafoil maererano nekuomarara kwepazasi, kurapwa, chimiro chezviyo, nezvimwewo. Kazhinji, mhangura yeED ine chimiro chezviyo chakamira. Mhangura yeED yakajairika inowanzova nechimiro chakakwirira kana kuti nzvimbo yakaoma kana ichienzaniswa neRolled Annealed (RA) Copper. Mhangura yeED inowanzo shaya kuchinjika uye haikurudzire kunaka kwechiratidzo.
Mhangura yeEA haina kukodzera mitsetse midiki uye kusakwanisa kukotama zvakanaka saka mhangura yeRA inoshandiswa paPCB inochinjika.
Zvisinei, hapana chikonzero chekutya ED copper mukushandiswa kwazvinoita.
Zvisinei, hapana chikonzero chekutya ED copper mukushandiswa kwesimba. Kusiyana neizvi, ndiyo sarudzo chaiyo mukushandiswa kwesimba kwakatetepa, kwakareruka kunoda kumhanya kwakakwirira. Chinhu chimwe chete chinodiwa ndechekudzora nekungwarira kwatinoshandisa "kuwedzera" plating pakuita kwePTH. RA foil ndiyo yega sarudzo inowanikwa kune huremu hwemhangura hwakanyanya (pamusoro pe 1 oz.) uko kushandiswa kwesimba kwakakura uye dynamic flexing zvinodiwa.
Kuti tinzwisise zvakanakira nekuipira kwezvinhu zviviri izvi, zvakakosha kunzwisisa zvakanakira mutengo nekushanda kwemhando mbiri idzi dzesimbi dzemhangura uye, zvakakoshawo, kuti chii chiri kutengeswa. Mugadziri haafanire kungofunga nezvezvinoshanda chete, asi kana zvichigona kuwanikwa nemutengo usingazosundi chigadzirwa chekupedzisira pamusika nemutengo.
