How to handle the through-hole components in SMT circuit board?
In a SMD mainly panel , there are always some capacitor need to insert by manual.
now we have a solution for this situation.
The S600-of is a revolutionary new concept from southern machinery that allows the placement or insertion of both surface mount and through-hole components.
it can load in normal SMD feeder and through-hole feeder at the same time.
Want more information,pls leave a comment.
We design and manufacture auto insertion machine，SMT equipment, and providing spare parts support
1, in the process of reflow soldering heat suddenly alarm prompt “temperature range of a certain temperature too low or a certain temperature and set temperature difference is too large”.
Aiming at this phenomenon, we can preliminary judgment fault will occur in the heating or part overheating protection, and so will all overheat protection switch sub let its failure, and start the machine, found that seems to be normal.After further analysis, under the condition of the overheating protection switch sub machine can work, but in the event of heating, the temperature rise too high a less protection of defense, will bring more serious consequences.In order to solve this problem, we must put 16 from heating unit to find out one or several thermal protection switch failure, we will each heating unit with this problem apart, examine its overheating protection switch, found problems the second heating unit overheating protection switch, with a moving contact bimetallic strip fixed weak, cause the moving contact and the static contact point contact is not good, or not at all contact (normally two contacts should be contact together and conduction).Because there is no the second heating unit of the spare parts to replace we will switch sub to ensure production run smoothly.To this can solve the problem, but as soon as possible to the broken overheating protection switch is off, so as to achieve the purpose of protecting the second heating unit.
2, if the downtime is longer, when it turns switched on again reflow computer tip ‘communication failure and can’t start the machine for a long time to let the heat.
Aiming at this phenomenon, we preliminary suspect as the communication line fault, then replaced the telecommunication lines, the question remains, so denied this conjecture.After further observed, when the communication is not successful, the lights on the status of the controller is not normal, orange lights should be flashing, and should not go out.Based on manual measuring line 1001 and line voltage between 1007 found that the voltage is not constant for the + 5 VDC, about + 2 VDC when communication is not successful, the problem is out of here, why the voltage is too low, the original control panel in the end of the machine here are two simulated load resistance, resistance ought to be ‘5’R , but actual value only two ‘2’R, but I have measured the value to change it into ‘5’ R problem is resolved.

The LED pick and place machine play an important role in manufacturing process, is the contemporary mainstream electronic assembly technology investment the largest and the most advanced production equipment, the production ability of SMT production line, and the greatest influence the efficiency of production equipment. In fact, the most fault, speed bottleneck largely from patch the process, so the development of the placement machine equipment is the most conspicuous. Currently has the number of SMT machine and advanced level, has become a corporate, regional, or national key symbol of electronic manufacturing capacity. Facing the current development trend of the placement machine under declare as follows.
1? the LED pick and place machine is developing toward the higher precision
Placement machine precision is refers to the placement machine X, Y axis navigation movement of the mechanical precision and Z axis rotation accuracy. SMT machine adopts precision mechanical and electrical integration technology control the mechanical movement components will crawl out from the feeder and after calibration institutions for the precise and reliable loaded on the circuit board. In order to produce the products with higher performance, first of all, facing a major challenge is more likely to improve placement accuracy of SMT machine. Below from the LED process began to speak with a higher accuracy of the LED placement machine could have LED the revolutionary impact of production in the future.
With the launch of the flip chip bonded technology, both are linked together by more stable metal convex welding ball to connect, saves the cost and greatly improves the reliability and the cooling capacity. Leads have the advantages of long service life, cooperate with the flip chip bonded technology is better than the traditional packaging technology of gold wire interconnection can play the advantages of LED, LED inversion welding technology, to realize the single chip and multichip module without gold line, solid crystal gel encapsulation, high brightness, high luminous efficiency, high reliability, low thermal resistance, good color uniformity, and many other advantages.
LED no gold wire packaging industry commonly known as the “packaging” encapsulation “free”. This process is to use the flip chip and PCB SMT joint directly, SMD encapsulation process is omitted, the flip chip directly with SMT method on the joint to the circuit board or bearer, because the chip http://www.onlinepharmacytabs.com area is far less than the SMD components, so the process need to be very sophisticated design.
LED placement machine in improving accuracy of future conditions on the basis of applied directly to the flip chip packaging process, it will be little revolution LED process, can save a lot of packaging costs, and greatly improves the production cost and shorten the production cycle, really high performance LED products to enter the general lighting market at low price. Will the LED placement machine directly applied to the LED process, very has the potential to become future technology trends.
2? the LED pick and place machine is developing toward the high efficiency production
Today, however, one of the most important characteristics of competition. It’s this competition, inspire people to explore innovation; It’s this competition, promote the development of science and technology with each passing day. In the course LED lighting market in full swing, the LED placement machine of high efficiency work must become its core competitiveness. High efficiency is to raise the production efficiency, reduce working time, increase production, create economic benefits. On the basis of the current main methods of improving efficiency are: strengthening the LED placement machine, automatic performance and improving the device structure and working mode.
3. the LED pick and place machine intelligent direction development
With the rapid development of Internet technology, the explosive growth of mobile intelligent terminal and consumer groups of young, intelligent is inevitable in the development of electronic industry especially in home appliance industry, the concept of intelligence has been frequently appear in our life, intelligent product is the most promising market in the future. Similarly, in the manufacturing, intelligent manufacturing equipment is the most promising manufacturing technology development.
Intelligent LED SMT machine has the following characteristics: man-machine integration, self-study, self-organization, maintenance, such as self-healing, super flexible, high automation level, improves the mental Labour to reduce the error in the process of production, so as to promote efficiency increase production capacity. Future LED placement machine is on the basis of computer intelligence technology makes his classes with more advanced thinking ability, to stick to the whole process of loading analysis, judgment, reasoning, and decision making, and can through the collection, storage, sharing and inherit the human experts’ intelligent and efficient to quickly provide the most suitable for flexible scheme. LED placement machine, motors and intelligent is bound to the LED production and technology have a great effect in the future.
For cost-saving or technical reasons (such as improved assembly), multiple circuit boards may be combined to form one large board, a “panel”. This panel is then produced just as a single large http://bestacnedrug.com circuit board. Consult with us to design the distance of LED chips is same as the spindle distance of placement head.
