摘要： There is provided a flow soldering process for mounting an electronic component onto a board by a solder material, which process is appropriate for using a lead-free solder material as the solder material. In the flow soldering process, thermal efficiency of flow soldering is improved in preheating step and/or solder material supplying step thereof. In one aspect of the present invention, a heating cover is located above a preheater, and the flow soldering is conducted while the board passes between the heating cover and the preheater. In another aspect of the present invention, a gap between a preheater and a solder bath is 20 to 60 mm. In yet another aspect of the present invention, a distance between a primary wave and a secondary wave is not larger than 60 mm.

摘要： There is provided a method which can conveniently estimate a quality of a lead-free solder material used for a flow soldering process. In the present invention, a differential thermal analysis curve of a sample of the lead-free solder material is obtained by utilizing a differential thermal analysis method, and thereby a quality of the lead-free solder material used for a flow soldering process is estimated based on the obtained differential thermal analysis curve.

摘要： A laminated core product producing apparatus wherein a projection is formed on part of a strip of core sheet material and core sheets are punched out of the strip and assembled in a linearly moving stack into the laminated core product by making use of the mutual fitting and crimping of the projections on the core sheets. The dimension of the laminated core product in the direction of the thickness of the core sheets is determined by controlling the intermittent punching out of the projections. A marking mechanism selectively marks a portion of the lateral side edge of a core sheet to be punched out, and at least one proximity sensor provided adjacent the stacked core sheets being assembled into the core product produces a signal corresponding to the distance of a marked core sheet from the head of the stack during movement of the marked core sheet along the stack. A timing signal generated each time a core sheet is punched out and assembled on the stack, a preset target value of the dimension of the core product, and information about the distance of the proximity sensor from the head of the stack, are also supplied to a control device, which calculates the dimension of the assembly of the core sheets and divides by the number of sheets counted to find the average thickness of one core sheet and adds the value of such average thickness for the number of core sheets to provide a cumulative value for each timing signal and controls the operation of a punching mechanism when the cumulative value exceeds the target value to avoid punching out a projection.

摘要： An injection molding valve nozzle comprises a nozzle head with a gate dividing a flow passage into two sections, a spool slidably attached to the gate and including axial grooves in its outer surface and a spring for urging the spool rearward. The valve nozzle is so arranged that the gate is closed by the spool because the grooves do not reach the gate upon lower pressure of resins below a certain level, but that the spool may slide forward to extend the grooves over the gate, communicating a front passage with a rear passage upon higher resin pressure above a certain level and that when the pressure differential between the front and rear passages decreases or the resin pressure descends below a certain level, the spool slides rearward by the spring for closing the gate.Thus, the gate is closed by the spool until the resin pressure rises up to a certain level. The engaging portions of the gate and the spool may be made long depending on the pressure and viscosity of the resin so that the gap between the gate and the spool can be determined to be approximately 10 .mu.m. Therefore, easy manufacturing of the valve nozzle is realized.Further, although the resins flow into the gap, the spool surely slides forward during injection to spout the resin by the resin from the rear without remaining, deterioration and dissolution. Therefore, the life of the valve is improved.
摘要翻译：注射成型阀喷嘴包括喷嘴头，其具有将流动通道分成两部分的门，可滑动地附接到门并且在其外表面中包括轴向槽的阀芯和用于向后推动阀芯的弹簧。阀门喷嘴布置成使阀门由阀芯关闭，因为在低于一定水平的树脂的较低压力下，槽不会到达浇口，而是可以向前滑动以将槽延伸到浇口上方，从而将前端在高于一定水平的较高树脂压力下具有后通道的通道，并且当前后通道之间的压差降低或树脂压力下降到一定水平以下时，阀芯由弹簧向后滑动以关闭闸门。因此，门被阀芯封闭，直到树脂压力上升到一定水平。栅极和线轴的接合部分可以根据树脂的压力和粘度而长，使得门和线轴之间的间隙可以确定为大约10微米。因此，实现了阀喷嘴的容易制造。此外，虽然树脂流入间隙，但是在注射期间，线轴可靠地向前滑动，从而从树脂向后喷射树脂，而不会残留，劣化和溶解。因此，阀的寿命得到改善。
