Title: Innovations of Franciscus Johannes De Klein

Introduction

Franciscus Johannes De Klein is a notable inventor based in Odijk, Netherlands. He has made significant contributions to the field of reflow soldering technology, particularly through his innovative patent.

Latest Patents

De Klein holds a patent for a reflow oven designed for soldering objects such as printed circuit boards. This invention establishes a temperature differential between the top and bottom surfaces of the board, allowing gases released from solder paste within through-holes to escape. This process effectively prevents the formation of voids in the solder. The oven features a flow of gas at a first temperature from an upper gas supplying means directed to the top side of the board. Additionally, a flow of gas at a second temperature is directed at the bottom side of the board by a lower gas supplying means. Notably, a portion of the gas from the upper supply can be captured and adjusted to the second temperature by the lower supply. The design includes multiple pairs of independently controllable gas supplying means arranged along a conveyor to create a specific temperature profile for effective reflow soldering.
