What is Design for Manufacturing (DFM)?
The main objective for our customer is to design a product that is efficiently and economically manufactured. Design for Manufacturing is concerned with reducing overall part production costs and minimizing the complexity of manufacturing operations.
PCBA Testing & Inspections
AOI inspection
Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew). It is commonly used because it is a non-contact test method.
Visual inspection
Visual inspection is a common method of quality control, by using either or all human senses such as vision, hearing, touch and smell and/or any non-specialized inspection equipment to ensure that the manufactured products being made to meet the quality requirements.
In-circuit Test
In-circuit testing (ICT) means an electrical probe tests a populated printed circuit board (PCB), checking for shorts, opens, resistance, capacitance, and other basic quantities which will show whether the assembly was correctly fabricated.
Electro-mechanical assembly
Electro-mechanical assembly is essential for the operation of all kinds of devices across a range of industries. It refers to any assemblies consisting of electrical and mechanical components or subassemblies that work together for a specific function.
Functional Test
Functional test is essential as it ensure the electronic product meets the required specifications and functions correctly. The functional test involves testing each device component to ensure they work perfectly together. That includes testing for compatibility, performance, reliability and safety features. By performing Functional Tests on electronic products during production, manufacturers can save time and money by avoiding costly defects or recalls later.
Burn-in Test
Burn-in is the process by which modules of a system are exercised before being placed in service. This testing process will force certain failures to occur under supervised conditions so an understanding of load capacity of the product can be established.
Conformal Coating
Conformal Coating is protective, breathable coating of thin polymeric film applied to PCBs. It provides protection against moisture and other harsher conditions. It can be applied in a number of ways including brushing, spraying, dispensing and dip coating.
Final Quality Control (FQA)
The final quality audit (FQA) process is to ensure the unit has gone through and passed all the manufacturing or test process and is in good quality.
This process not only includes visual checking of the unit (i.e. labels has been placed properly, no scratches, no dents, all LED/lights are functional) but also checks that the correct firmware and version plus configuration has been loaded properly. It must power up according to specs as well.
