Automation Benefits
The purpose of this document is to improve printed circuit board
design and layout by detailing the basic considerations associated
with the electronic assembly process. Experience has
shown that applying these design principles produces efficient,
reliable board designs.
Automatic component insertion provides the consistency required to
ensure the highest levels of circuit board quality, throughput, and
process control. When properly planned and implemented, automatic
component insertion provides significant cost savings in the
printed circuit board assembly process.
The benefits realized from automating circuit board assembly processes
span all areas of manufacturing. Ultimately, all of these
benefits result in improved products and reduced production costs.
Three key inputs affect the economics and logistics of PC board
assembly: (1) the circuit boards, (2) the equipment used to assemble
the boards, and (3) the components to be inserted. By precisely
understanding and standardizing these three primary elements,
manufacturers can improve the quality of the finished boards,
increase the throughput of the assembly equipment and the system,
and more precisely define the process control standards to provide a
basis for future applications. Standardizing these elements reduces
process variability, which leads to increased insertion reliability,
improved product quality, enhanced system price/performance and,
ultimately, reduced production costs.

Automatic Stencil cleaner to improve SMT quality
WHAT’S IMPORTANT TO YOU
When selecting an SMT screen/stencil-cleaning process, it is critical to prioritize the deciding factors that are
most important to the user.
• Can the process effectively clean fine and ultra fine-pitch apertures?
• What flux do I need to clean now and will it be necessary to clean a different flux in the future?
• Can the process support these potential changes?
• Can the process clean dry as well as fresh paste?
• Are there other objects to clean, such as misprints, pallets, adhesives, etc.?
• What is the environmental impact?
• What is the capital investment?
• What is the operating cost?
• Are there any health or safety hazards to consider?
• Does the process have any detrimental effects on the stencil?
• What is the maintenance and potential downtime?
• Are there any special handling or storage requirements for flammable or hazardous chemistries?
• Who will take responsibility for correcting the process if it fails to perform?
1, No need electronic power, no fire and detonate caused.
2, Simple operation, only Start, Stop and Reset, that is all….

SMEMA: What is it?
In the surface mount electronics industry, manufacturing each type of product requires a variety of process steps, and therefore a multitude of process equipment. This production equipment varies greatly not only from manufacturer to manufacturer, but also in its function. However, the different equipment must be able to work together to produce the final goods. Difficulties arise when equipment is not standardized and cannot communicate. To help cross these barriers, the Surface Mount Equipment Manufacturers Association (SMEMA) was formed. SMEMA is a nonprofit organization composed of manufacturers of equipment or software used for surface mount board production. In this article we will give a brief overview of SMEMA and define the mechanical and electrical interface standard implemented on equipment manufactured
SMEMA’s objectives ·
promote standards for the interface and operation of production equipment · assure users that equipment adhering to SMEMA standards interfaces easily · advance surface mount technology and promote its uses · investigate http://modafinil200mg.net areas where the association can benefit member companies
Interface standard
The mechanical and electrical interface standard provides an equipment specification for single board transfer systems of surface-mounted PCBs. The standard defines the electrical and mechanical concepts of the machine interface. The latest SMEMA-published standard is version 1.2. This article will highlight the SMEMA electrical interface. A mechanical interface overview will appear in a future issue of Product Perspective.
Signal overview, descriptions, and timing
The following diagrams provide a simplified explanation of the electrical signals and their locations, timing, and terminology. The diagrams refer to conveyor-type products, but the concepts are the same for any SMEMA interface. Please note that these drawings are not the actual SMEMA specification, but are simplified interpretations to help you understand the interface. The actual SMEMA specification is more specific; details on how to obtain this specification are provided at the end of this article.
