Re: Ly ir8500 station good or?

Thanks
9 min. to reach max.temp, then station notify me and I take chip out.

Re: Ly ir8500 station good or?

As soon as I changed flux, there are nice results for desoldering. No chip warping anymore.

Re: Ly ir8500 station good or?

Hi,
thanks, problem was probably with flux. I used alpha rma7 flux but its rosin based. I tried clean pcb after removing chip (lead free) and this flux was overcooked. Very hard to clean from pads so not good for desoldering. Will test it with kingbo flux filled to syringe.

Re: Ly ir8500 station good or?

Hi,
thanks for informations. I have more pcbs for testing. Up to this moment no bga was popcorned but there is a bit problem with warping of the bga chip with lead free solder balls - not much but I am detailist. For chip with lead solder balls it was ok but there is lower melting temp and different profile. At the moment I have 2cm top heater height from pcb but my heater is elstein 150w , I will try adjust height.

My idea is make semiautomatic station only set mode solder/desolder , temp profile for lead solder / lead free...

Hw is finished , now I am adjusting temperature profiles.

Re: Ly ir8500 station good or?



It was made mainly for my personal usage but I have some uP. At the moment there is problem with more components (for example elstein top ir heater). Original head from LY have unevenly heated plate, waiting for elstein one....

Re: Ly ir8500 station good or?

Hi,
I am working on customised t-862 low cost station. My goal is made proffesional station from this low cost. My design is inspired by ir8500. It have my own controller with STM32 ARM uP and I am looking what features to implement. I am using thermistors instead of thermocouplers in combination with 14bit ADC for accurate temp. measurement. Possible to connect 6 thermistors and one thermocouple for solder iron. I am waiting for bigger bottom ceramic ir heater at the moment.

New controller have possibility:
- connect up...
