Camera module, molded circuit board assembly, molded photosensitive assembly and manufacturing method thereof

A camera module, a molded circuit board assembly, a molded photosensitive assembly and manufacturing method thereof are disclosed. The camera module includes a molded base which is integrally formed with a circuit board through a molding process, wherein a photosensitive element may be electrically connected on the circuit board and at least a portion of a non-photosensitive area portion of the photosensitive element is also connected by the molded base through the molding process. A light window is formed in a central portion of the molded base to provide a light path for the photosensitive element, wherein a cross section of the light window is configured to have a trapezoidal or multi-step trapezoidal shape which has a size increasing from bottom to top to facilitate demoulding and avoiding stray lights.

Method for preparing pyroelectric polymer film based on combined process of solution casting and uniaxial stretching

A method for preparing a pyroelectric polymer film based on a combined process of solution casting and uniaxial stretching is disclosed. The pyroelectric polymer film is firstly prepared by solution casting, afterwards, the casted film is subjected to uniaxial stretching when the film is in a semi-cured state (wet film). Thus a larger stretching ratio (>10) at a lower temperature (even at room temperature) is realized. Without undergoing a further poling process, the as-stretched film does have a fairly, good pyroelectric performance. Moreover, the surface of the stretched film is smoother and has fewer surface defects.

Provided is a method for producing a polyethylene-based resin extruded foam sheet by extruding and foaming a foamable molten resin composition formed by kneading a mixture containing a low-density polyethylene, a physical blowing agent, and an antistatic agent, wherein the foam sheet has a thickness in a range of from 0.05 to 0.5 mm, and the antistatic agent is a polymeric antistatic agent having a melting point whose different from the melting point of the low-density polyethylene is in a range of from 10 to +10 C., and having a melt flow rate of 10 g/10 min or more. This method enables a novel polyethylene-based resin extruded foam sheet to be obtained that is of high quality such that formation of a small hole or a through-hole has been reduced or eliminated, and has both excellent strength and a shock-absorbing property despite a very small thickness even in medium- or long-term continuous production, and besides, exhibits a sufficient antistatic property, thus suitable as a glass plate interleaf sheet.
