Abstract

Pellicole fotosensibili atte a formare una maschera di saldatura sulla faccia di una scheda di circuito stampato sono più facilmente laminate sulla faccia della scheda effettuando l'evacuazione dell'aria e la pressatura meccanica all'interno di una camera a vuoto, evitando una completa fluidificazione dello strato di resina fotosensibile. Successivamente l'assieme è riscaldato in modo da fluidificare lo strato di resina fotosensibile che, per effetto della pressione atmosferica, si conforma completamente alla superficie della scheda. La ritenzione del foglio di copertura della pellicola fino al momento di riscaldare l'assieme a pressione atmosferica, facilita l'esecuzione di trattamenti atti a preservare l'integrità delle "tendinature". Il metodo risulta vantaggioso sia nel caso di pellicole sottili conformabili sia nel caso di pellicole più spesse (planarizzanti).
