摘要： Methods and apparatus are disclosed for efficiently and precisely adhering and centering particles on tacky areas on a surface containing an array of tacky and non-tacky areas. These methods and apparatus for particle attachment and centering involve holding and heating of the surface containing an array of tacky and non-tacky areas with particles adhered thereon for a period of time and at a temperature to allow the particles to adhere and center to the tacky areas. The surface containing the array of tacky and non-tacky areas can be heated either prior to, during or after a step of contacting the array with particles. Either discrete sheets or a continuous moving web of material having a surface containing an array of tacky and non-tacky areas can be employed. Each tacky area of an array of tacky and non-tacky areas has a size and bonding strength suitable for adhesion of one particle thereto in formation of an array. The array is populated with conductive-particles, is useful in the precise placement of particles on contact pads of electronic devices, such as circuit boards in semiconductor applications.

摘要： Methods and associated apparatus are disclosed for use in mounting particles on and de-mounting particles from a substrate having an array of tacky and non-tacky areas. The particles can be either electrically conducting or electrically non-conducting. Selection of electrically conducting particles is preferred. The substrate having an array of tacky and non-tacky areas can either be electrically non-conducting (e.g., a dielectric substrate) or electrically-conducting. The methods involve use of first and second electrode plates with the substrate therebetween, the plates having applied thereto a direct current potential, which potential in preferred embodiments is reversed in polarity for a number N of cycles. Methods and articles are disclosed using an electrically conductive surface adjacent the tacky and non-tacky areas to minimize static buildup on the particles and tacky and non-tacky areas.
