Design for manufacturability ,We consider the manufacturability of our products from the beginning of design, improve the straight-through rate and reliability of our products, and make them easier to
manufacture while reducing manufacturing costs.
Design for manufacturability is based on the idea of parallel design, in the design phase of the product to consider the process requirements of manufacturing, testing requirements and the rationality
of assembly, through the design of means to control the cost, performance and quality of the product.
In general, design for manufacturability includes three main aspects: PCB board manufacturability
design, PCBA assembly design, and low manufacturing cost design.
PCB board manufacturability design is mainly from the perspective of PCB board manufacturing, consider the manufacturing process parameters, so as to improve the straight-through rate of the
board and reduce the process communication costs. For example, the line width, line spacing design is sufficient to meet the real requirements of the factory, hole to line, hole to hole distance
compliance, these points should be considered clearly at the time of design.
PCBA assembly design is to consider how to standardize the layout, how to properly design the PCB package, device thermal balance and other issues from the perspective of PCBA assembly and
processing. PCB packaging is mainly based on the consideration of soldering performance, components and PCB pads need to match, as well as the consideration of the device pins, whether it is
Low manufacturing costs, is also very important. a product’s market competitiveness. a large factor is dependent on its cost, based on cost, from two aspects, the first is to choose the manufacturing
process, the designer needs to be as good as possible from the simplest; the second is the need to master the factory’s quotation law, each factory has its own set of quotation logic, perhaps the
factory’s quotation rules will deviate, but the vast majority of them are more or less the same
we are found the eginners needs consider many questions. some companies has ten or one hunders design rules. if you use the tools. all handel by human. the faults rates are very high!
In summary, it is not difficult to find that design engineers need to consider a lot of things, a slightly stricter company, they may have dozens and hundreds of design rules, if not with the help of tools,
all human control, the chances of error is very high.
However, the current market process inspection tools and software is not much, a few commercial software, most of the high price, many small and medium-sized enterprises are difficult to afford.
Well, the emptens how about do making anylics ? there have one list, people check list one by one. but effect is too low. and also make errors easy. so many companies jump it direct .
do not gy check.
So, how do companies typically do their manufacturability analysis now? –They have a checklist and manually check each one. However, this is very inefficient and also error-prone. So much so that
some companies just skip this item and don’t process inspection.
The main values that can be brought to engineers are as follows.
01. Standardized design: After analysis by Huachou DFM software, the software will appear to prompt, if the design is not standardized, or risky, the software will provide rationalization suggestions.
02. Improve quality: If the design is standardized, then the quality can be naturally improved.
03 .Reduce communication: It means to reduce the communication between design and production side, and the design specification can reduce the communication cost afterwards.
04 .Shorten cycle time: It can improve the straight-through rate of production, which can shorten the product development cycle and also achieve the effect of cost reduction, so Huaqiu DFM can be
used as a bridge between design and production to make manufacturing simpler.
