PCB Assembly for Agricultural Machines
Product Classification: PCBA
Product Name: RAS100_V1.3
Pcb sheet information: size: 149.9*101MM four layers FR4, board thickness 1.6MM, copper thickness 1OZ, immersion gold, black oil white, perforated plug oil
Production process: lead-free process
Process flow: smt+dip+ assembly + packaging
IC pre-production burning: 1 customer incoming material AT24C02, STM8S105K4 will burn these two C, we confirm whether there is burning.
Solder paste requirements: Ag3.0/Cu0.5/20-38uM
A/B surface patch: 1.J15 surface first paste, because the second fixed surface will stick the PCB surface when the second surface is attached, so that the solder paste can not be brushed, so the four fixed feet of J15 must be cut off 0.5 in advance. Mm.
2. Four steel holes should be sealed, and 100% top height defects occur in the previous batch production.
3. Pay attention to the printing effect of BGA. It is necessary to check the quality of each tin bead tin. The furnace temperature must be confirmed to be OK. Strictly control the straight-through rate and find that the straight-through rate is low and the line is improved immediately before it is put into production.
