CONTROL SYSTEM DESIGN OF SMT PICK AND PLACE MACHINE “

“CONTROL SYSTEM DESIGN OF SMT PICK AND PLACE MACHINE “

Here we would like to discuss original design of control system of complete SMT Pick and Place machine.

Proposed Design

Southern Machinery Provide different type of SMT Pick and Place Machines according to the requirements and Specification of Global Clients however one of our machine consists of four DC motors. Three of these motors are used to move machine head along X-axis, Y-axis and Z-axis. Fourth motor is for rotating SMT component clockwise and anticlockwise. Encoders are attached to shafts of all four motors. These motors are connected to motor drivers through electric connections. Encoder outputs routed to the EISA card mounted on EISA port. Data bus from EISA card is attached to external main board. Motor drive cards are mounted on main board. In addition to different signals for actuating different relays, data bus also carry control voltage signals. These analogue voltage signals vary in the range from +5V _-5V. Duty cycle of PWM signal vary with changing magnitude of this analogue signal.

Main Board

This is the part of our machines control system which acts as a bridge between EISA card and machines motors and feeders. All data signals and control voltage signals from EISA control card terminate at the main board. Depending on purpose which it serves, main board has several main parts. These parts are discussed here one by one.

Power Module

· This part of main board is associated with rectifying input AC voltage to DC voltage as shown in figure 5.1. Main functions of this part are following:
· Supply Power to motor drivers at 35v
· Supply 12V for powering operational amplifiers ICs. Supply 5V for powering TTL logic ICs.
· Supply 15V for actuating feeder plungers as shown in picture.

Protection Module
· This part contains relay switches to turn AC power on or off from software control as shown in picture.

Limit Switch Module
· This part deals with providing power source to proximity switches and receiving output of proximity or limit switches as shown in picture

Data Transmission Module
· This module receives data from some external data source through any programmable protocol (RS232 etc.) and routs that data to EISA card as shown in picture.

Feeder Relay Module
· This module consists of 15 relays. These relays actuate respective feeder plunger when decoded data is received. Each rely is connected with single plunger thus it controls one feeder at time as shown in picture.

Decoder Module
· This module receives 4 bit data from EISA card and decodes this data to 16 bits. 15 bits of decoded data are used to actuate one feeder at time as show in picture.
PWM Generation Module

· This part consists of two PIC18F2431 microcontrollers. These microcontrollers receive analogue control voltages and generate PWM. Microcontrollers are programmed such a way that duty cycle of PWM is function of input control voltage.

Motor Drivers

· Motor driver used in our project are H Bridge Bipolar type drivers. Input signal to motor driver are either bipolar PWM or analogue control voltage as show in figure
· 5.8. Motor driver use two kinds of power sources. One source is for driving motor
· when bridge is in conducting state. Motor driver receive 35V from main board for this purpose. Motor driver receive isolation supply from external transformers rated for 10V at output as shown in figure 5.9. This isolation supply voltage is rectified to DC voltage.

Solder Paste and Its Application in SMT
Solder paste or solder cream is simply a suspension of fine solder particles in a flux vehicle. In electronics industry, solder paste is used in Surface Mount Technology (SMT) to solder SMDs on to the Printed Circuit board. The composition of the particles can be tailored to produce a paste of the desired melting range. Additional metals can be added to change paste compositions for specialized applications. Particle size and shape, metal content and flux type can be varied to produce pastes to varying viscosity.

Solder Paste Screen Printer
Some of the major features to consider when selecting screen printer for solder paste are the maximum size of the circuit board that can be handled, controls of accurate screen alignment and repeat ability of print, and the board hold-down mechanism. Considerable progress has been solder paste dispenser, screening and stenciling for pastes on substrates. Each method of dispensing solder paste has its own pros and cons but the most widely used method is stenciling for both rework and large scale production. Southern Machinery is a well-known supplier of screen printing equipment.

Stencils for Solder Paste Application
There are three main ways of making stencils for solder paste:
Chemical etching
Laser cutting
Electroforming
Chemical etching is the oldest, most widely used, and least expensive option. Laser cutting and electroforming, especially the latter, find appeal in applications where precision is paramount. In addition to the type of stencil, the type of squeegee blade is very important. Metal blade squeegees are widely used because they require less maintenance than rubber squeegees.
Availability of Solder Paste
Solder paste is available in both leaded (with lead) and lead-free (with no lead) forms. It can be no-clean or water soluble. With no-clean solder paste, there is not need to clean the board after soldering. Water soluble solder paste is easily soluble in water with no harm.

Happy Chinese New Year

Chinese New Year is coming, and you’re probably thinking about the delicious homemade food, relaxing afternoon naps, and great time with friends and family. Don’t let these illusions blind you, though. You are walking into the apocalypse, and no one is on your side.

1. The Two-Faced Parents
For the first two days at home you’ll be their sweet baby, and starting from the third day they want to throw you away. You wake up at 9 and they say you are lazy. You wear ripped jeans and they say you are dirty. You eat too little then you are not giving them “face”. You eat too much then they say you are fat and will be single forever. There’s no chance of winning to argue with your parents. The only advice that could possibly help is to just wait – wait until you become a parent and take revenge on your own kids.

2. The Drama Queen Aunties
“How much money do you make now?” "Why are you still not married?” "When are you buying a house in Beijing?” Boom boom boom – drama queen aunties just released a trifecta. “My son got the 2nd place in the final!” “My daughter married a government official!” “I am having a grandchild in a month!” Whoops – drama queen aunties unlocked the advanced attack – kid comparison, it’s a killer. It’d be stupid to take it head on, but you can out-flank by dropping another drama bomb:“My mama don’t like you and she likes everyone.”

3. The CNY Friends
The CNY friends are those people who you are only friends with during Chinese New Year. However, they never come with good intention. “Hi how are you! Btw my wedding is next Monday.” Hand in ¥600. “How have you been? Oh right, it’s my baby’s 100-day ceremony tomorrow.” Hand in ¥800. “Long time no see! What a good timing that it’s my husband’s funeral today!” Hand in ¥1000. Are they the CNY friends, or CN¥ friends? The only way to get away from them is to go on the offense. Spread the rumor that you are diagnosed with brain cancer and are looking for friends to borrow money from. It will make them disappear.

4. The Annoying Kids
Eating up your favorite snack, drawing a penis on your expensive bag, and screaming at you for red pocket money – the annoying kids seem to be always high on ecstasy. Don’t even try to complain, otherwise they bring in the drama queen aunties to help:"He is just a kid! You are an adult! You are supposed to take care of him!" Well played, kids and aunties. The proper way to deal with annoying kids is to deal with them like the stupid hot girl at the party: you give them a lot of tasty alcohol and take them to bed – they won’t know a thing.

Thanks for reading this article, and hope you have an amazing holiday whether you are sipping cocktails by the beach, or playing MaJiang and chain smoking at home.

Independent Upper and Lower PID Temperature Controls

Independent Upper and Lower PID Temperature Controls for Each Heating Zone Permit Precise Temperature Profiling

S-R1000’s heating zone temperature controllers have an accuracy of ±1°C and, in conjunction with a high-speed blower adjacent to each heat source for maximum convection, ensure a ΔT of ±2°C across the PCB assembly. The Series diffuser design provides low-velocity, low-turbulence air flow to prevent component shift or disturbance.

Optional thermocouples can be attached at critical locations on the PCB and connected to three built-in inputs (standard) on the oven for communication with  control software for accurate, real-time temperature profiling to match any solder paste manufacturer’s specifications.

CR-10000 SMT Reflow Oven Pin over mesh conveyor

Pin-Over-Mesh Conveyor Meets Virtually Any Product Specification or Production Requirement

The S-R1000 is supplied as standard with an adjustable-rail, pin-type conveyor system that handles PCBs up to a maximum of 450 mm (17.7″) installed over a 570 mm (22″) stainless-steel mesh belt. The pin conveyor permits inline and double-sided processing. The mesh belt is ideal for fast changeovers.

To eliminate the possibility of jamming or dropped PCB assemblies, all components are constructed of high-quality, high-strength, stainless steel and are built to maintain dimensional tolerances at the high temperatures of lead-free processing.

Advanced automatic chain lubrication and motorized width adjustment are standard features on the pin conveyor. Automatic width adjustment of the pin conveyor, based on the parameter settings for specific reflow programs, is available as an option. For processing of larger PCBs at higher lead-free temperatures, a center support system is available to prevent board warpage.

Conveyor speed is programmable from 400-1800 mm (16″-71″) per minute to accommodate any process requirement.

Nitrogen Atmosphere Compatible Models Widen Lead-Free Processing Window Through Reduced Oxidation

While the debate over air or inert reflow atmospheres continues, as an option, offers the S-R1000 in a nitrogen-compatible configuration for manufacturers who want the flexibility for soldering in both environments.

Most experts agree that the reduction of oxygen through the introduction of an inert gas (usually N2) will allow a wider process window and provide better solder joints through reduced oxidation. The enhanced flow design of the heating chamber in the S-R1000 nitrogen compatible system lends itself to efficient heat transfer and ensures low nitrogen consumption while maintaining O2 levels between 300-1000 ppm.

CR-10000 reflow oven internal water-chilled recirculating cooling system available

Internal Water Cooling Provides Maximum Control Over Critical Cooling Rates Required By Some Lead-Free Solders

Because the higher liquidus temperatures required by lead-free solders approach the limits of many SMT components and PCB assemblies, more aggressive cooling is often required to reduce peak temperature exposure times. Some recent studies also indicate that cooling rates have a significant effect on solder joint grain structure.

For these reasons, an internal water-chilled recirculating cooling system is available for the S-R1000. It allows users to alter cooling rates to meet solder paste manufacturers recommendations to a much greater degree than is possible with the exclusive use of air cooling.

CR-10000 reflow oven real-time profiling

Advanced Functionality and Process Management Capability

Operation and control of all  reflow systems is accomplished through an attractive, colorful, visual user interface that features a full-screen, virtual view of the system with display of pre-set and actual zone temperatures, system status and conveyor speed.

The Windows-based operating system and control software includes advanced functions for temperature profiling, timed automatic startup and shutdown, audible and visual alarms, and password protection.

A PC-controller with 15″ flat screen monitor, keyboard and trackball allow unlimited storage and networking capability.

All systems employ UPS battery backup to ensure removal of all product from the oven in the event of a power outage.
