Method and apparatus for soldering inspection of a surface mounted

A method of and a device for controlling a counter of a rolled material on a multi-high rolling mill with which method and device very accurate shape control can be attained with certainty and in high responsibility. A strip shape of a rolled material in its widthwise direction on the outgoing side of the rolling mill is detected by a strip shape meter, and the detected shape and a strip thickness are synthetically evaluated using a total performance index. Operation amounts for a strip shape controlling actuator and a strip thickness controlling actuator which make the value of the total performance index minimum are always found out, and the actuators are controlled simultaneously in accordance with the operation amounts to control the strip shape of the rolled material. The apparatus comprises a saddle receiver the vertical position of which is controlled by a roll gap controlling device in accordance with an estimated value to change the gap between upper and lower work rolls of the rolling mill.

In a method of fabricating an aluminum surface for applying mirror-smooth fabrication to the surface of aluminum or aluminum alloy by combining an electrolytic anode dissolving effect to the surface and a polishing effect of removing the protruded portions of passivated films formed on the surface to be fabricated by lapping with abrasive grains, the voltage between the aluminum material and the tool electrode is set within 2.1.+-.0.3 V, an electrolyte at less than 10% concentration is used as a passivation type electrolyte, the urging pressure of the tool electrode to the surface is set to less than 2.0 kgf/cm.sup.2 and free abrasive grains with the average grain size of less than 1.0 .mu.m are used as the abrasive grains. The temperature of the electrolyte is preferably set to lower than 15.degree. C. The polishing material may comprise non-woven abrasive cloth made of ultrafine fibers.
