WebCOB (chip on board) refers to assembly of bare die onto a laminate substrate, such as FR-4, with wirebonding. This is sometimes referred to as MCM-L. DCA(direct chip attach) refers to flip chip attach of a bare die to a laminate substrate. It is distin-guished from COB by the use of flip chip bonding rather than wirebonding. DCAis also a form WebIn contrast, the chip surface with bonding pads are looking downward (Face-down) with flip chip assembly method. The bonding pads are connected to a substrate via solder bump, ACF and so on. Following benefits can be obtained with our laser assisted bonding machine for flip chip: Depress thermal stress that caused by long reflow time.
