SMT process for LED display
A. Material Testing: check the amount of materials, specifications, models, quality, performance is in line with the requirements
B. Brush solder paste: solder paste thawing, mix well, steel screen adjustment, solder paste printing, check the solder paste surface even on the whole
- Paste components: first paste small and then paste large, pay attention to the location, model, direction, polarity, uniformity
D.QC: error-free parts, Wrong Pole, leakage, dislocation, solder paste uniform good, components level alignment
E.Over-reflow soldering: Temperature Control, speed control, shift, plate, plate to hold gently flat, check tin surface, maintenance machine.
F.Holding Tin Face: holding tin, tin heap, less tin, virtual welding, oblique welding, off-soldering, repair errors and leaks
Problems in the production of LED Display
1. The whole module is not bright: the module is not connected to the power supply: input cable plug-in reverse; input and output reverse; power supply positive and negative pole connection reverse
- Module is not bright transmission normal: protection circuit damage solution can be 74HC138 foot 4 and foot 5 short circuit.
- Every third line is dark: one is broken.
- Second Row Bright two lines: B signal problem, check whether there is a virtual welding, replace the ICA signal in the same way
- Upper half normal lower half bright or not bright: check whether the data signal is the same way.
Factors of display market price
The market price of LED display is average, ordinary color is 6000-8000 yuan per square meter, double color 3000-4000 yuan per square meter, single color red 2000-3000 yuan per square meter. Small spacing full color, the price is as high as tens of thongs of even.
