Smt Production Process Introduction Gkc Led Display

Smt Production Process Introduction Gkc Led Display Smt key process flow. 1、solder paste printing. its role is to leak solder paste or patch glue onto the solder pad of the pcb to prepare for the welding of components. the equipment used is solder paste printing machine, located in the front of the smt production line;. Ems partner. gkc has ranked no.1 in electronics manufacturing service among chineseled display manufacturers for 10 years in a row. we provide manufacturing, procurement, partial design and logistics and a series of services.

Smt Production Process Introduction Gkc Led Display Gkc’s indoor fixed led display f9 series p1.25 and p1.56 products adopt cob process and smd process respectively.the module size of these two products is 150×168.75mm, and the box size is 600×337.5mm.their contrast ratio is 1000000:1, the gray scale level is 14 16bit, and the refresh rate is 3840hz.their small pitch is suitable for various indoor scenario, and their high contrast and high. In this article, we will specifically talk about smt pcb assembly, including the definition of smt manufacturing and the step by step guide for the smt manufacturing process in electronics production. what is smt manufacturing. smt means surface mount technology. smt components are very small size packages like 0201,0402, tssop, dfn, qfn, qfp, etc. Step 1. transfer pcb into solder paste printing machine. so you are standing beside the start of an smt assembly line. the first machine is a loader that holds all the pcbs in line for smt manufacturing. the loader automatically sends the bare pcb one by one through a transmission rod into a solder paste printing machine. Here is a method for placing tc’s to measure smt joint temperatures: before the component is soldered to the board, drill a small hole through the pad of the joint to be measured. insert the thermocouple from the bottom of the board. hold the thermocouple tip flush with the top surface of the board.

In order to increase the smt assembly yield on the pcb, the mini leds are grouped into $4(2\times 2\ \text{pixels})$ in one smd (surface mount device), i.e., a total of 12 r, b, and g mini leds. a pcb ( $132\text{mm}\times 77\text{mm}$) is designed and fabricated for the drop test of the mini led package. thermal cycling of the mini led smd pcb. Led display is a kind of flat panel display which is composed of small led modules. it is the largest and most widely used large screen display technology at present. it can be used not only indoors but also outdoors, waterproof, windproof and rain proof. such as outdoor advertising large screen, led information release, stage background screen.
