I-3M Polyimide Film Tape 5413|Itheyiphu ye-3M yangempela

I-3M™ Polyimide Film Tape 5413 yenziwe ngefilimu ye-polyimide nokunamathela kwe-silicone. Isetshenziselwa i-PCB solder masking nezinye izinhlelo zokusebenza zokushisa okuphezulu.

"Sebenzisa i-3M™ Polyimide Film Tape 5413 ukuze uthole imaski ye-solder ye-PCB kanye nezinye izinhlelo zokusebenza zokushisa okuphezulu phakathi kwebanga elingu-73 °C kuya ku-260 °C. Le tape enombala we-amber, enogqinsi ongu-2.7 mil yenziwe ngefilimu ye-polyimide kanye ne-adhesive ye-silicone. Iphinde ibe ne-polyethylene yetheyipu enamathelayo enciphisa umgogodla wokunamathisela wekhadibhodi enamathelayo esikhundleni sokunamathisela okunamathiselwe kwekhadibhodi'. ukuhlanzwa, okukuvumela ukuthi ugcine ukukhiqiza kuphezulu ifilimu yePolyimide ihlinzeka ngokukhishwa okuhle kakhulu njengoba ingathambisi futhi ihlale izinzile emazingeni okushisa aphezulu - ukuvimbela ukusebenza kabusha kwezindawo ezizungezile zivikelwe ngenxa yalokhu kubambezeleka kwelangabi lamakhasethi, amakhemikhali nokumelana nemisebe, ukunciphisa izindleko zokushintshwa.
