The reason why the chip mounted is called "flip chip" is relative to the traditional wire bonding connection method (WireBonding) and the post-balling process. The electrical side of the traditional chip connected to the substrate by wire bonding faces up, while the electrical side of the flip chip faces down, which is equivalent to turning the former over, so it is called "flip chip".   The essence of flip chip is that on the basis of the traditional process, explosion   proof   lighting   area and the electrode area of the chip are not designed on the same plane. At this time, the electrode area is mounted toward the bottom of the lamp cup, which can save the process of wire bonding. , but the precision of this process of solid crystal is relatively high, and it is generally difficult to achieve a high yield.   Requirements for flip chip:   The base material is silicon; The electrical surface and solder bumps are on the lower surface of the component; Und...

With the maturity of SLA light-curing 3D printing technology, some smart tablet manufacturers have begun to use 3D printers to include in their enterprise plans. The 3D printing tablet model is completely proofed according to the original shape of the plan, with low error. Compared with the traditional prototype, it saves the cost of proofing, shortens the manufacturing cycle of the prototype model, ensures the confidentiality of the product development planning scheme, and greatly improves the work efficiency and product development. According to the feedback from the manufacturer using the SLA 3D printing prototype of Harbin Industry, the business volume has increased rapidly and the labor cost has been saved by 40% since the use of the D printer prototype for about a year since March. Let's see how 3D can help hand board manufacturers save 40% of labor costs! The hand board is also called "model" and also called "first board" many years ago ". It is no...

Influence of 3D printing on mechanical manufacturing and automation 3D printing technology is widely used because of its flexibility and convenience. Printing technology involves different molding processes and material classification. There is no uniform standard now. According to the volume of the equipment, it can be divided into desktop, medium and large 3D printers; It can be divided into: aerospace, military, industrial, civil 3D printers, etc. 3D printing propsis a comprehensive technology combining mechanical engineering technology, computer software technology, 3D model technology, data processing technology and other disciplines. To a certain extent, it meets the needs of the development of mechanical manufacturing, and brings ultra-fast molding speed, unparalleled printing speed, high material utilization rate and short production cycle in industrial production, greatly improving the degree of automation and digitalization. At present, XYZPrinting partpro150_ XP, mech...

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it...
