Method for controlling glue flow

Номер: US20120138222A1
Автор: William Halliday

A method for controlling a contact angle between a glue and a surface of a substrate during manufacture of microchip packages is disclosed. The method includes applying a glue to a surface of a substrate, and placing an electrode in electrical connection with the glue. A potential difference is applied between the electrode and the substrate. The potential difference is applied across the glue and causes a contact angle between the glue and the surface of the substrate to be altered.

The present invention is a novel method of preparing copper sheeting for exposure to UV or optical light in the process of manufacturing flexible printed circuit boards. This method seeks to remove the need for the highly complex, costly, and capital-intensive use of collimated UV lights and vacuum chambers in conventional FPCB manufacturing by preparing copper sheeting for non-vacuum non-collimated UV exposure with a relatively trivial method using clear vinyl stickers, conventional toner-adhering decorative foil, and UV reflective glue. This in turn will “democratize” the design, development, fabrication, production, and distribution of advanced electronics that depend upon the use of high-precision FPCBs.

Methods of selectively filling apertures

Номер: US6066889A
Принадлежит: International Business Machines Corp

A novel method of filling apertures in substrates, such as through holes, is provided. The method utilizes a photoimageable film, and comprises the following steps: applying a photoimagable, hole fill film over the apertures; reflowing the hole fill film to flow into the apertures; exposing the hole fill film to actinic radiation, preferably ultraviolet light, through a phototool, which preferably has openings slightly larger than the diameter of the apertures; then at least partially curing the hole fill film; and developing the hole fill film to remove the unexposed hole fill film. An advantage of the present method is that the apertures may be selectively filled. After the apertures are filled, the hole fill film is cured, preferably by baking. Thereafter, the substrate is preferably subjected to further processing steps; for example, nubs of cured hole fill film are preferably removed. If desired, the substrate is circuitized. If desired, features are gold plated, such as for example, electrolessly gold plated. The hole fill film preferably has solids which comprise 0 to about 20% of a thixotrope and about 80% to about 100% parts of an epoxy resin system; the epoxy resin system comprises: from about 10% to about 80% of phenoxy polyol resin which is the condensation product of epichlorohydrin and bisphenol A, having a molecular weight of from about 40,000 to about 130,000; from about 20% to about 90% of an epoxidized multifunctional bisphenol A formaldehyde novolac resin having a molecular weight of from about 4,000 to about 10,000; from about 35% to about 50% of a diglycidyl ether of bisphenol A, preferably halogenated, and having a molecular weight of from about 600 to about 2,500; and from about 0.1 to about 15 parts by weight of the total resin weight, a cationic photoinitiator. The invention also relates to circuitized structures produced according to the method.
