LED display manufacturers SMT placement machine shop process
LED display manufacturers SMT placement machine shop process I recently went to Zhongshan Guzhen and Siu Lam, where the world's most famous LED industry, but also met many customers do not understand the LED industry's SMT workshop process, here I Introduce, hope to be able to invest a little bit to help LED industry customer.
Led lamp / lamp with the production process through the patch, plug-in, post-welding, testing, filling glue, assembly, commissioning, packaging and other eight major processes, the following is the introduction of each sub-process.
First, SMT (LED Mounter)
1. Material inspection ------------ check the amount of material, specifications, model, quality, performance meet the requirements of 2. Brush solder paste (red plastic) --------- solder paste thawing, mix well, steel net adjustment, solder paste printing, check paste surface evenly. Patch components (hand patch) ------ After the first small pieces of large pieces, pay attention to location, model, direction, polarity, uniformity 4. Inspection surface (QC) -------- no error parts, wrong pole, missed parts, misplaced, solder paste is evenly attached, and the components are level and aligned 5. Over-reflow ------ temperature, speed, put the board, the board, the board should take light, check the tin surface, maintenance machine 6. Executive tin surface (plastic surface) --------Implementation of tin, heap tin, less tin, false welding, oblique welding, desoldering, repair error repair, DIP (LED plug-in machine)
1. Cut the lamp foot ------ adjust the light slot, knife position, speed, sub-file, classification, clear label, machine grounding, pay attention to anti-static 2. Stickers ------ cover manual pad, screw hole position 3. Plug-in (manually insert the lamp) ------- pay attention to PCB direction, lamp color, polarity, position, pay attention to anti-static 4. Check the insert (QC) ------ no wrong direction, wrong position, wrong pole, wrong color, high and low light, pay attention to anti-static 5. Pallet on the -------- folder class positioning, pay attention to the direction, no oblique light, partial lights, high and low lights, clip lamp, pay attention to anti-static 6. Over wave soldering ------ adjusting temperature.
