How do you guys solder Fine Pitch chips to a PCB?
Because some companys use ROSIN FLUX Liquid and its really hard to remove the fine pitch chip because its sticky from the rosin and it lifts up the pcb pads
The water-soluble Flux Liquid seems to be better cause its no sticky at all
I use a Flat angle blade on my soldering iron tip
How i solder in the Fine pitch chip is i tack in all the 4 pins of each 4 conners on the chip
If i SLIDE the soldering iron tip from #1 across the other fine pitch pins it creates alot of SHorts because its fine pitch very close pins
The Rosin Flux makes it worse creates more shorts plus its very sticky
When i was cleaning the Rosin flux off the fine pitch pins with a brissle brush it bent all the pins to the sides because some of them wasn't solder to the pads so it ruined the chip
I think using a small paint brush with rubbing achol. was much more GENTLE to use on the fine pitch pins without bending them to the sides
How do you guys clean with >? and what kind of brush to be gentle on the fine pitch chips?
What types of flux you guys use?
