The revenue of circuit board and electronic component manufacturing in the U.S. exceeds $44 billion. This is an enormous and continually growing industry within the United States. As technology continues to take a primary role in people’s lives, the needs for constantly manufacturing and improvements is essential. For many companies, small batch pcb is essential to their operation and growth.
Board designers use computer-aided design systems with special software to layout the circuit pattern on the board. The most common boards have four layers, six layers, eight layers or ten layers. However, multi-layered boards are not limited to these sizes. The highest number of possible layers is 42. However, these are extremely complex boards that most common systems do not need.
There are two methods used to connect the circuits on each side of a double-sided board: surface mount technology or through-hole technology. This isn?t to say one method is better than the other, just that two exist. When placing a small batch pcb order, it is important though to know what method will be used in case it becomes an issue down the road.
70% of all printing problems are caused by quality issues with the surface assemble. The temperature curve, for example, plays a significant role in the soldering quality. When dealing with pcb fabrication, quality holds the utmost importance. This is also why pcb inspection is essential with all manufacturing.
Prior to appropriate design software, Mylar sheets were used to design printed circuit boards. This would create a transparent photomask of the design. The growth of this industry exploded from just over seven million dollars to over 60 million since the year 2000.
Improved design techniques and machine-assembly for all size orders directly impacted that rapid growth. Some assemblers now have a turn-around time of less than five days, which is 75% faster than the industry average according to some reports.
Heavy copper PCB are now an option due to these advanced techniques. Many designers use one to two ounce copper. However, manufacturers can produce up to a six ounce thickness. If you have a design you want to try, you can pursue pcb prototype assembly; these kinds of services are common when building a relationship with a manufacturer.
