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. LED display is based on the project, the path to decide, for display text, or play advertising video, indoor or outdoor, viewing distance and so on, need to consider. The price of the display is also affected by these factors.
