What is Electronic Prototyping, Testing and Mass Production?
Electronic prototype; It is one of the first examples prepared to evaluate the specific functions and application conditions of a design. In mass production, the aim is to repeat the same design with defined methods and acceptance criteria. The operation of the prototype does not alone indicate that the production process is ready.
What questions does the prototype answer?
Prototype work allows examining the feasibility of the requirements. Initial checks may include opening the card, operation of basic functions, and communication of interfaces. Additional considerations may be required for conditions of use, mechanical fit, and expected behavior. If it is defined at the beginning which questions will be answered by the prototype, design changes can be made with clearer justifications after testing.
What do SMT and DIP mean?
SMT refers to surface mount technology. In through-hole mounting, component legs are inserted into holes on the board; DIP is the name of a package with two rows of legs and is sometimes used to describe this assembly area in daily use. A board can contain components from both assembly types. The selection is made based on component packages, design and manufacturing method.
Are AOI and functional testing the same thing?
AOI is an optical inspection approach; Can be used to control visible assembly features. Functional testing evaluates the expected outputs by running the specified functions of the product. It should not be assumed that all functions of a card that has passed optical inspection are correct. The scope of testing is determined by the product; For example, it should be written which inputs, outputs and communication functions will be tested and under what conditions.
Delivery list for transition to mass production
It is important that the component list, production files, assembly information, software version and test records are up to date. The use of equivalent components should be evaluated separately in terms of design and testing. An example acceptance list might associate device ID, test result, and software version. A general promise for cost or delivery time should not be made until the production quantity, lead time and acceptance criteria are clarified.
Technical questions and answers
Is an employee card sufficient production verification?
A single example does not represent all production variables. Acceptance criteria, testing scope and production process are also evaluated.
Does every electronic product undergo the same tests?
No. Intended use, functions, risks and delivery requirements determine the test plan.
Can the equivalent component be used directly?
Compliance must be checked in terms of packaging, electrical characteristics, software and conditions of use.
What files are prepared for production?
Depending on the manufacturer and project scope, card printouts, component list, assembly data, software version and test instructions may be requested.
