METHOD FOR PROCESSING PLASTIC PACKAGED ELECTRONIC DEVICES

摘要

METHOD FOR PROCESSING PLASTIC PACKAGED EKECTRONIC DEVICES The subject invention is a method for processing a plastic packaged electronic device with soldered leads. The solder has a critical temperature which if exceeded more than once results in its oxidation. The method comprises protecting the device with a carrier, and baking the device and carrier in a low pressure environment and at a temperature sufficiently high enough to drive off moisture previously absorbed by the plastic but lower than the critical temperature of the solder.
