Hello Shyeya,
The Electronics and computer engineering at Thapar University is a very good option as Thapar is a very know college in india. Now talking about the placement, 75% students get placed in the core like IT and consulting. The average placement for the year 2017 was 6 lakhs with 70% placement.
I recommend you to join ECE in Thapar and try to keep your CGPA above 8.4 and you will surely get placed in some good companies.
I hope you will find my answer helpful.
All the best.
