Stencil Nano-Coatings

NanoScale prevleke (E . g ., teflon, silicijev karbid) izboljšajo sproščanje spajke paste z zmanjšanjem površinske energije na 15-20 mn/m . premazo<0.3mm pitch components, improving transfer efficiency by 30%. Durability exceeds 100,000 prints without degradation. Application methods include plasma-enhanced CVD and electrospray. Benefits: Reduced bridging in QFN packages, elimination of manual wiping downtime. Testing confirms >95% stopnja polnjenja zaslonke za 01005 komponente . Omejitve vključujejo zahteve glede enakomernosti prevleke pod debelino 50 nm .
