| I need some advice concerning reflow of a BGA-292. Since I am not ready to change my entire process to no-clean, I decided to place the lone BGA-292 on a proto run using our BGA re-work station. The pcb is a moderately dense, single-sided, 8-laye

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c
