Abstract:
1. A solder reflow oven apparatus for soldering of components onto printed circuit boards comprising: A. an oven housing means defining at least one heating chamber means therewithin to facilitate reflow soldering of components to printed circuit boards located therein, said oven housing means defining a chamber inlet means in fluid flow communication with respect to said heating chamber means, said oven housing means also defining a chamber outlet means spatially disposed from said chamber inlet means and in fluid flow communication with respect to said heating chamber means, said oven housing means including a first side wall means extending from said chamber inlet means to said chamber outlet means, said oven housing means further including a second side wall means extending from said chamber inlet means to said chamber outlet means at a position laterally spatially disposed from said first side wall means to define said heating chamber means therebetween; B. a heating means positioned within said heating chamber means for generating heat therewithin; C. a conveying means extending inwardly into said heating chamber means through said chamber inlet means between said first side wall means and said second side wall means and extending outwardly from said heating chamber means through said chamber outlet means, said conveying means defining an upper support surface adapted to carry printed circuit boards thereon for movement therewith through said heating chamber means in order to facilitate reflow soldering of components to the printed circuit board; D. an air circulation means secured within said heating chamber means and adapted to urge movement of air within said heating chamber means adjacent said heating means for heating thereof and to urge movement of air adjacent the printed circuit boards traveling therethrough on said conveying means for reflow soldering of components thereto, said air circulation means including:
