Description

  The present invention relates to skill acquisition and skill improvement involving manual work, etc., in particular, a skill acquisition method for skill acquisition applicants related to skills for performing soldering, etc. The present invention relates to a certification system and a printed wiring board for teaching materials used as teaching materials.

  There is remarkable progress in the development of electronics technology today, and electronic devices are becoming smaller, lighter and more multifunctional, while electronic components are becoming faster and larger in capacity. In particular, integrated circuits, circuit boards, components, and the like have made remarkable progress, and these electronic components are required to be mounted with high density and high integration.

  Along with this, the mounting method of electronic components on a printed wiring board has changed from a conventional lead insertion method to a surface mounting method in which electrical connection / bonding is performed using a conductor pattern and the surface of the electronic component. As for the soldering required for electrical connection / joining, automation such as flow and reflow has progressed, and today they have become mainstream, and as a result, manual soldering work has been performed manually. It is decreasing.

  However, manual soldering is still necessary in the part retrofitting process, equipment wiring for correction / repair, and the production of prototypes. In addition, although automation of flow and reflow is progressing, it is essential to acquire knowledge about soldering technology through manual soldering work in order to train workers and improve their skills. . Furthermore, knowledge acquired through manual soldering is indispensable for the intermediate inspection in the automated soldering process, the appearance inspection after completion of the process, and the cause investigation when a defect occurs.

  Training of workers including soldering work is generally performed by a method unique to each company.

  For example, regarding the training and training system for workers, the skills to perform each standardized work process in the production line were distributed to the network terminals by distributing educational tools that allow the workers themselves to learn themselves, and the skills were standardized into a database. There has been proposed a worker education system that determines a worker's skill rank based on skill data and executes training for each skill rank when necessary (see Patent Document 1).

In addition, regarding work instructions for product assembly work, the details of work contents are displayed on the PC screen according to the proficiency level, taking into account the effect on work efficiency due to differences in the proficiency level of workers. It has been proposed (see Patent Document 2).

  FIG. 3 is a diagram showing an example of the relationship between the certification test and the training course in the skill certification system of the present embodiment.

  As shown in FIG. 3 (a), the skill certification system of this embodiment is a "basic soldering education" for new employees and workers who start a new soldering work, which is necessary for personnel changes, etc. 100, “soldering skill training” 101 classified into the 4th, 3rd, 2nd, 1st, and special classes, and the “certification test” 102 that certifies the skill level for each class.

As shown in FIG. 3 (b), "Soldering basic education" 100 is a classroom lecture based on educational materials with 2 hours as a guide. "Soldering skill training" 101 is a printed wiring board for teaching materials. It is used to actually acquire the soldering skill by hand, and the standard time is set according to the class.
When each worker performs “soldering skill training” 101 for each class task at each workplace, supervisors (educators) in each workplace identify the situation as shown in FIG. An “assessment” 103 is performed to determine whether to take the certification test 102 or to continue the same skill training again.

  When it is determined that the certification test 102 should be taken, as shown in FIG. 3 (d), a paper certification based on "soldering basics" and a certification test 102 for each grade based on "soldering practice" are taken. If you pass the grade you have taken, you will be issued a badge that identifies your skill level and will be registered in your skill map as a personal history. On the other hand, if the test is not passed, the class held by the test taker will be reviewed.

  Here, in this embodiment, the “certification test” is classified into the fourth grade, the third grade, the second grade, the first grade, and the special grade, but it is not necessarily limited to this.

  FIG. 4 is a diagram showing, as an example, a soldering skill system table that systematically summarizes the soldering skill elements stored in the DB.

  As shown in FIG. 4, in the soldering skill element, the shape and conditions of the components are systematically organized for each mounting target component 111 for each class 110 representing the soldering skill level. Further, the soldering skill system for each class 110 is linked to the classification task 120 in the certification test stored in the DB, and the parts are linked to the parts list 121 stored in the DB.

  The soldering skill elements include, for example, a process that requires manual soldering based on a procedure manual creation system that is constructed separately from the soldering skill certification system of this embodiment (lead component, surface mounting, etc.) Parts “SMD”, jumper, hot melt, etc.), skill items required for prototype remodeling (lead increase, size difference correspondence, tortoise shell, etc.), and items that have been problematic in quality control in the past, They can be created by taking into account the difficulty of work.

  For example, for lead parts, “fillet was formed due to insufficient amount of solder”, “thermal” in the past against the conditions of “large land”, “solid land”, and “through zigzag”. Soldering content is extracted so that quality control problems such as “because of shortage will lead to smoldering” and “short circuit occurred due to difficulty in soldering” and systematize the skill elements of soldering Can be arranged according to class.

  According to the “standard skill map” 130, the fourth grade skill is set so that it can be acquired in three days. And the person who acquired the 4th class skill can practice for half a year and take the 3rd class skill. Persons who have acquired Level 3 skills can practice and work for Level 2 skills after about one year. Then, work practice is performed again, and after about 2 years, the first grade skill can be taken. And, with more practical experience, you can take the first grade skills. Therefore, a training system has been created with the aim of acquiring special skills in about three years, including practical experience.

  Here, the period set in the standard skill map is an example, and the entire period can be shortened within a few weeks by taking advantage of the characteristics of the skill certification system connected by the network.

  In addition, on the “standard skill map” 130, “subjects and target levels” 131 and “training items” 132 of each class are displayed. For example, Level 4 is “Practical and ready-to-use low-level skills that only lead parts are acquired from joining the company to the hand soldering process and acquire a level that can be practiced in 3 days”. , “Skill training for general retrofit parts”.

  Level 1 is “Highly skilled and learns the level that all soldering elements registered in the procedure manual creation system can be mounted”, and performs “skill training on mounting of fine pitch components”.

  Special grades are "high skills that can be modified, mastering advanced mounting skills that are different from normal, which occur during assembly and modification of prototype PCBs", and "fine pitch parts that are unusual. , "Skill training that can cope with bad mounting conditions, such as those requiring aerial wiring, raising QFP leads, and narrow component spacing".

Based on such information, the standard of the course for which you want to acquire skills is determined, and when you click on “Application for Skill Certification”, a dialog box for entering the necessary information such as “name, address, affiliation, telephone number, e-mail address, years of experience, etc.” on the web page A box is displayed.
