ASMPT offers SMT placement solutions for any type of production. From highly flexible small-sizes manufacturing to high-volume mass production, SIPLACE solutions set benchmarks in performance, accuracy and flexibility, with smart software, placement heads and component feeding systems that can be shared across machine platforms.
Recently I was asked how asmpt siplace pick and place machines actually work, and similar topics are often discussed, and most of what people say about asmpt siplace pick & place machines is basically the following :
Advantages: high precision, fast speed, XYSR 4-axis are scale counting, Z-axis has a bottom sensor, quality assurance .
Disadvantages: expensive machine, many small problems, easy to break, expensive parts, technicians want high wages .
In fact, I would like to say that I have played the vast majority of asmpt siplace pick and place machines , machine production years spanning close to 20 years, the asmpt siplace pick and place machines are still more favourable, for the machine’s shortcomings most of the objective factors lead to, as long as the following aspects of good control will reduce a lot of problems .
I. Hardware
- Asmpt siplace pick and place machines Power supply, it is recommended that all SMT machines are connected to the UPS and voltage regulator, grid voltage pollution caused by unstable voltage, leading to burn boards, power outages will damage the computer hard drive, as well as the furnace boards have the risk of scrapping and so on.
2. Asmpt siplace pick and place machines gas supply, compressed air must be good dust and water in addition to oil, refrigeration dryer, adsorption dryer, filter core are not less, compressed air water and oil pollution airway, the old opportunity to drip from the vacuum generator to the board, drip to the SLEEVE on the RV reading head, resulting in the report of the RVD frequently, the new machine directly burned out the vacuum generator .
3. Asmpt siplace pick and place machines temperature and humidity, SMT equipment, the best temperature is 24 ± 4 degrees, humidity 45% -75%, the temperature is too high leading to equipment downtime, a variety of small problems appear frequently, lagging, humidity is too low to produce static electricity, leading to throw the rate of material soared .
4. Asmpt siplace pick and place machines cleanliness, SMT dust degree is crucial to the quality of the furnace after the 0201 above the material is best to run in the 30W class clean room, high-speed machine are afraid of dust, dust is big one is easy to lead to suction nozzle clogging, flying material leakage frequently, the second is to affect a variety of sensors, especially BE sensor, resulting in the thickness of the small material test is not allowed, the third is prone to accelerate the wear and tear of the slider and the guideway, especially the X series DP.
5. Asmpt siplace pick and place machines maintenance, now many companies do not pay attention to the maintenance of equipment, busy when a month or even months without maintenance, sometimes monthly maintenance is also to do some weekly maintenance content, which is why the overseas machine more than ten years ago, the old machine is still in good condition, people are in accordance with the standard maintenance process to do .
6. Asmpt siplace pick and place machines engineer skills, many companies do not control the above aspects of production, the machine just bought the first two or three years nothing wrong, followed by more and more problems, the quality is getting worse and worse, maintenance costs are getting higher and higher, the boss can not afford to spend a high price to hire a good project .
A problem regardless of whether the engineers and technicians have no qualifications to dismantle the more you dismantle the worse, the more bad the more you dismantle the more you dismantle the more you dismantle the more you dismantle the more you dismantle the more, with a couple of years on the whole is not like the way .
II. Software
The Asmpt siplace pick and place machines software side is mainly just one thing, viruses, where do they come from, USB sticks. I would strongly suggest using a LAN share to guide the programme, rather than copying it around on a USB stick, which is a line spreading disease? The first major source of poison, Siemens program stored in the SQL database, line control poisoning leads to any problem will occur, such as what material unexplained reversal, the line control to change the programme on the machine can not take effect, OIS connection is not available, the image can not be back to the line control, the programme can not be transmitted to the machine .
As long as you do the above, I believe that your machine is becoming more and more efficient and less and less problem .
