    • PURPOSE:To manufactue a laser-marking device to an IC, etc., which can decide acceptable or rejectable marking, by arranging a laser light-receiving element at a specific position. CONSTITUTION:Pulse beams from a laser generator 1 are projected to the surface of an IC3 through a mask 5, and a mark 29 is put. In this case, beams passing through two holes 19 bored to the mask 5 pass through air gaps 25 at both ends of the IC3 through an optical system 6 and are projected to a pair of light- receptors 7, marking work is stopped when there is no signal from both light- receptors, and missed marking is prevented. The laser generator 1 is triggered when an index 10 for the IC is detected by another light source 27 and a light- receptor 28, and a mark is put at an accurate position.

    • PURPOSE:To increase the adhesive strength of ink, and to prevent the disappearance of marks for displaying quality by forming a smooth surface and a crape surface to the outer surface of a resin and shaping these marks on the smooth surface when the marks are put on the resin seal surface of a semiconductor element by a laser-marking method or a bar code. CONSTITUTION:When a large number of leads 3 for external connection are sealed by using a resin 1 while being projected to the outside, a die for a resin seal, sections thereof corresponding to the upper surface and side end surfaces of the resin 1 are formed to a crape shape through electrical discharge machining and a lower surface thereof is formed to a specular shape through grinding machining, is used. Printed marks 2 are formed on the crape surface of the upper surface obtained by the die, and bar codes 5 are marked to the specular surface 4 of the lower surface through a laser-marking method. Accordingly, beams perform irregular reflection only at the code sections 5 when beams are irradiated to the specular surface 4, and informations are read positively. That is, a process in which the specular surface is generated at the same time as the resin sealing and the process for forming specular surface again is omitted.
    • 目的:提高油墨的粘合强度,通过在树脂的外表面形成光滑的表面和表面,防止标记显示质量的消失,并在标记放置时在光滑的表面上形成这些标记 半导体元件的树脂密封表面通过激光​​打标法或条形码。 构成:在大量外部连接用引线3通过使用树脂1同时向外部进行密封的情况下,形成树脂密封用模具,与树脂1的上表面和侧端面对应的部分 通过放电加工成为绉状,并且其下表面通过研磨加工形成为镜面形状。 在由模具获得的上表面的绉纹表面上形成印刷标记2,并且通过激光打标法将条形码5标记到下表面的镜面4。 因此,当光束照射到镜面4时,光束仅在代码部分5处执行不规则反射,并且正面地读取信息。 也就是说,省略了与树脂密封同时产生镜面的过程和再次形成镜面的处理。
