Kunzwisisa chinangwa chePCB lamination
2024-06-26
1. Kuomesa Brown
Chinangwa:
Shandisa kemikari kuoxidize pamusoro pemhangura kuti igadzire ganda re oxide (brown cuprous oxide), iyo inowedzera nzvimbo yepamusoro kuti iwedzere simba rekubatana.
Kuchenjerera:
1. Mushure mekuoxidizing yebrown, bhodhi rinofanira kutakurirwa nekukasika uye kupiswa nelaminate. Kana rikasiyiwa kwenguva yakareba, rinogona kunyorova uye rinosangana neCO2 mumhepo kuti rigadzire carbonic acid, iyo inonyungudutsa brown oxide layer, zvichikanganisa simba rayo rekubatanidza uye kuwedzera njodzi yekudzikira kweganda.
2. Bhodhi rine jira gobvu remhangura (≥2oz) uye bhodhi risina chinhu rinofanira kubikwa kuti ribvise hunyoro hwakawandisa.
Zviyero zvekubika: 120℃±5℃×120 min
2. Pre stack
Chinangwa:
Zvichienderana nemirayiridzo yeMI, unganidza bhodhi repakati nePP pamwe chete.
Maumbirwo akafanana ebhodhi rine mativi mana
3. Kurodha bhodhi
Chinangwa:
Isa mapuranga ese akarongwa kare uye akasungirirwa ari ega paplate yesimbi zvakatevedzana, kazhinji nemabhodhi e4-6pnl ekugadzira paplate yega yega.
4. Kuravira
Chinangwa:
Kuburikidza netembiricha uye kumanikidzwa kwakati, maitiro ekusimba kwePP kubva pachikamu chesimbi kusvika pamvura anoitwa kuti bhodhi repakati, PP nefoil yemhangura zvibatanidzwe pamwe chete.
5. Kuburitsa zvinhu
Chinangwa:
Bvisa bhodhi rakaiswa laminated kuita maPNL, woatonhodza.
6. Kuboorera chinangwa cheX-Ray
Chinangwa:
Bata nzvimbo yemufananidzo wechikamu chemukati kuburikidza neX-Ray irradiation yeChishandiso cheX-Ray, wobva waboora maburi ekuisa nzvimbo kuburikidza nekuboorwa kwemuchina.
