T-962A Infrared reflow oven
Inside front panel - LCD on the left, control PCB, small fan
Inside rear panel - solid-state relay for heater control, mains transformer.
All wiring is in heat resistant sleeve, but I wonder how effective that is when the wire
inside is PVC...!
PCB close-up.
Major surprise is it uses an ARM based MCU - LPC2148. This is just bizarre, as it doesn't need anything like this amount of processing power, even for the graphic display. Maybe there was an available graphics driver, or they use the same processor in other products perhaps?
Slightly surprised to see the LM2575 regulator - presumably due to teh draw of the LCD backlight.
PCB to the right is a triac controller for the mains fan in the rear. I wonder if the unpopulated parts are for the heater control on the smaller model.
Tons of hot-glue everywhere to retain connectors, even the ones that already have retention clips....
Not very impressed with large amounts of what looks like masking tape to keep
the foil away from the eletronics...
Cute little display of temp profile, but the user interface and firmware in
general is as abysmal as I've come to expect from a cheap Chinese product like this.
Written to do the bare minimum to get it out the door and no more - zero thought. I hate
stuff like this.
Note partial characters to the right of the temp indications where the previous 3-digit
display hasn't been cleared.
A surprise at the
rear - What appears to be a Papst fan, not an obscure Chinese thing. I do wonder about the
felt-tip pen marks on it though...
The manual is such a masterpiece of 'Chinglish" that I had to put a copy for your enjoyment. Interestingly there was a CD in the box with a copy of a manual with much better English. Err. why didn't they just print that one....?
