摘要： A method for assembling a semiconductor package includes a rapid cooling step after post mold curing of an encapsulation material. The rapid cooling step includes blowing chilled, compressed air over the package for about two minutes. The rapid cooling step does not require any clamping pressure be simultaneously applied to the package. The rapid cooling step reduces a temperature of the encapsulation material from a curing temperature to the cooled temperature within a maximum period of less than five minutes. By using rapid cooling, as opposed to cooling the package under a clamping pressure with ambient air, package warpage due to CTE mismatches is prevented.

摘要： A no-lead type semiconductor package is formed by attaching a die to a top surface of a flag of a lead frame and then taping a bottom surface of the flag and leads of the lead frame. Die bonding pads are connected to the leads with wires and then the assembly is put in a mold chase and encapsulated with a plastic material. The mold chase has protrusions between the flag and the leads of a lead frame, and between the leads themselves, which causes indentations to be formed between the leads and between the flag and the leads. The method is particularly useful for making quad flat no lead (QFN) devices and power-QFN type devices.
