Abstract: Disclosed is a shielding process for SIP packaging, including: providing a circuit board; cutting the covering layer to form half-cut trenches separating different SIP packaging modules from each other, and to form grooves in each single SIP packaging module; forming a metal overlay, the metal overlay on an outer surface of the SIP packaging module and at positions where the half-cut trenches are located constituting a conformal shielding, the metal overlay at positions where the grooves are located constituting a compartment shielding; and cutting the half-cut trenches to obtain a plurality of SIP packaging modules that are separate from each other.

Abstract: Provided are the use of poly(N-isopropylacrylamide-co-butyl methacrylate) in preparing an embolism material for blood vessels, an embolism material for blood vessels and the use thereof in preparation of drugs. The embolism material for blood vessels comprises poly(N-isopropylacrylamide-co-butyl methacrylate) and a dispersion medium consisting of an electrolyte, a contrast agent, a pH regulator and water. The concentrations of the polymer, electrolyte and contrast agent are respectively 5-30 mg/ml, 0.1-30 mg/ml and 100-350 mg/ml based on iodine. The embolism material for blood vessels is suitable for embolization therapy of tumors in hypervascular and parenchymal visceral organs.
