How do you think pakistan manages all that?and what are "various" pakistani labs specializing in various fields?
Before we do a little research on what is available openly, Ill repeat verbatim what a senior official told me regarding the philosophy they have "Only R&D what you cannot purchase from the open market".
Starting with that philosophy, you can move onto what facilities exist at government levels.
But here is the problem. Take this snapshot, it is likely that this area has over 30 facilities that has everything from micron level scanning, banks of 3d printers, CnC fabrication, MEMs fabrication(purchased from abroad).. along with a security.
From this shot, all it looks like is just a residential area, infact if you go there it is a residential area... the only giveaways happen when you start seeing barriers in certain locations, guys in plainclothes with earpieces that unless you are looking for them you wont know. And this is a shot from a hustling and bustling city.
This for e.g. was designed and built within a double basement facility that had this on top.
So how do you identify labs? How do you know what is going on when the parliament and civilian government is NOT authorized to view what is being allocated and for what to these institutions.

Which is why I pointed you to a university whole faculty includes people who have been part of the above.. and hence you get certain clues as to what might be worked upon.
Another thing is the level of access Pakistan has to facilities in China. Which is unprecedented.. take this for e.g.
Ta'eerun, Software Defined Radio (SDR), SDR
The Radio system listed on top by this private firm(indecently related to the University I posted in the previous post) was designed at the firm.. from the boards, casing, supply.. and software.. throughout..
The manufacturing of it however was outsourced to a Chinese firm which created the designed product and delivered it.
Which brings us back again. Why not do this at home? Well, it could be done.. but when it is cheaper to have it done via outsourcing.. why not do so?
So a lot of your queries regarding the research needed for producing some of the critical components for advanced design gets eliminated from the process when you can simply order off the Chinese "catalogue" or have them make it on order.
So if you would need to invest.. as an example.. say $1 billion to set up a complete MEMs R&D facility.. you can use and design on the Chinese one for around $20 million.
But this has serious disadvantages; for starters.. Pakistan ends up lacking these facilities for shortening the time needed to coordinate design. In addition, the over reliance on the Chinese facilities means that many "gaps" end up appearing when certain technological advances are needed. Which gets exacerbated in case even the Chinese do not have that information or in certain cases are unwilling to share it.
So ill end up to the original premise of your question.. where are all the facilities? Where is the work being done?
One can start here.. and then go through various universities to where the publications keep going on..
Research Publications
But at the end of the day.. there is really nothing going on anywhere.. and a lot going on everywhere.
Not the best policy, not the best answer either.. but that is all I have from my own experience.
