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.

Assembly inspection training

Inspection to IPC-610D With its comprehensive criteria for printed circuit board assemblies, IPC-A-610 is the most widely used inspection standard in the electronics industry and has earned an international reputation as
the source for end-product acceptance criteria for consumer and high reliability printed circuit
assemblies. Now updated to lead free, and available in many languages, IPC-A-610 has been
embraced by original equipment manufacturers and electronics manufacturing services companies worldwide.

Manual Board Handling Options Workboard Holders

Manual Board Handling Options Workboard Holders

Workboard holders hold the PCBs for the machine to perform work. Workboard holders hold the PCBs in a position that is oriented, and allow for quick removal of the PCBs. The workboard holders allow from one window up to four windows. More windows in the workboard holders enable faster machine operation by reducing transfer time. For a single-board workboard holder, the machine rotates the board into the assembly area, begins operation, and then rotates the board out when work is complete. While the board is being reloaded, the machine stops while waiting for a new board. Throughput improvements can be achieved by utilizing to a two-window workboard holder. With a two- window workboard holder, while one window is in the assembly area, the other window is available to be unloaded and re-loaded. Therefore, the machine idle time is limited to the time required to rotate the workboard holder under the assembly head. This rotation takes one second. The throughput gain can be further improved by implementing a four-window workboard holder that requires only a 90-degree rotation by the table to get a new board under the work zone. This reduces the transfer time down to a half second.
