Welcome to inquire! Contact: Miss Shi. Difficult biggest flip chip when the then advanced skills integrated into specification SMT components, skills encountered. In a package assembly use, widely used in flip-chip BGA and CSP, BGA and CSP has been chosen, although the lead - Structural skills. Assembled at the board level, the selection of flip chip can bring many advantages, including reducing the scale components, functional progress and reduce costs. Unfortunately, the choice of flip chip makers add funded skills needs, in order to qualify for the machine, add special equipment for flip chip technology. These devices include flip chip can be satisfied the needs of high precision placement system and underfill dispensing system. Also includes X-rays and pan system Zhuhai smt, used for after reflow soldering detection and analysis after the next hole filling. Pad depicting, including the shape, the size, and mask limit smt, and can be produced on the test of (DFM / T) and the satisfaction of the needs of capital are crucial aspects. PCB board flip chip (FCOB) is mainly used in small-scale into the product of vital Shantou smt, such as Bluetooth module components or medical devices. A Bluetooth module printed board, during 0201 passive components with the same flip chip package with integrated skills. The flip chip assembly equipment and 0201 the same high-speed placement and disposal can be surrounded by a solder ball placed near the package. It can be said that in the specification and implementation of advanced SMT assembly line skills, such as a good one. Printing type 1) Printing: steel engraved hole to be determined according to the type, the substrate properties of the parts, the size and shape of its thickness and the hole. The advantage is speed, high efficiency. 2) Dispensing mode: dispensing is the use of compressed air, the red plastic through special dispensing head points to the substrate, the size of the gel point, how much, by the time, pressure and other parameters to control the tube diameter, flexible dispenser function. For different parts of Guangzhou smt, we can use different dispensing head, set parameters to change, you can also change the shape and number of the gel-point, in order to achieve the desired effect, the advantage of convenience, flexibility, and stability. The disadvantage is that easy to have brushed and bubbles. We can job parameters, speed, time, pressure, temperature adjustment, to minimize these drawbacks. 3) needle to the way, the film is a special needle, dipped in a shallow plastic dish each needle has a gel point, when the gel-point contact with the substrate, will be out of the needle, the needle through the glue can shape and diameter to change. Curing temperature 100 ℃ 120 ℃ 150 ℃ curing time of 5 minutes 60 seconds 150 seconds typical curing conditions: Note: 1, the curing temperature is higher and longer curing time, the adhesive strength of the stronger. 2, due to the adhesive patch temperature will vary depending on the size of the base part and placement position change, therefore we recommend to identify the most suitable curing conditions. Red plastic storage: store at room temperature for 7 days, at less than 5 ℃ storage greater than one in June, at 5 ~ 25 ℃ can be stored more than 30 days. Because SMT patch red plastic with itself affected by temperature viscosity, flow, wetting and other features, so SMT patch red plastic have a certain use conditions and standardized management. 1) red plastic have specific serial numbers, according to the feed quantity, date, species numbered. 2) red plastic to be placed in the refrigerator for 2 ~ 8 ℃ to save, to prevent the temperature changes, the impact properties. 3) red plastic warmed 4 hours at room temperature requirements next time, in order to use the FIFO. 4) For the dispensing operation, red plastic hose to be degassed, for unused disposable red plastic should be back in the refrigerator, the old and the new plastic glue can not be mixed. 5) To fill in the return temperature record sheet accurately, warmed people and warmed time, users need to confirm the completion of warmed before use. Typically, the red plastic can not use expired.
