You will have to discuss this with the manufacturer/PCB companies. If you can use Filled & Capped vias then you will not have any issues with soldering unless to much or to little solder is used. We recommend filled and capped in most cases.

Some PCB companies have caused problems in this regard. Will there be any problems with assembly?

You need to use vias to cat acsess to some of the pins on the nRF52840. If you do not plan to use all the pins then you do not need to add vias to all the pins.

There should be no issue having vias in the area where arrow points to as long as the design follows what we use in our reference design.

In the PCB circuit I marked in the pictures, vias appear to have been added to the marked areas on the pads of the nRF52840. But this way of adding to PCB manufacturers can continue, he says. Do we have additive services on the pads when designing this PCB?

Merhaba,
Daha iyi cevap alabilmek icin sorunuzu ingilizce yazabilirsiniz. "Via-in-Pad" teknolojisi her PCB üreticisi yapamayabilir, cünkü lehim pastasi sürüldügünde, eger via icinde minik hava baloncuklari kaldiysa, lehimleme esnasinda isitildigina, hava baloncuklari sisip lehimin ve cipin kaymasina sebep olabilir, bu da kisa devrelere sebep olabilir. O yüzden bazi PCB üreticileri bunu tavsiye etmez. Tabi bu, her zaman böyle olacak anlamina gelmez, sadece böyle bir tehlikenin bilincinde olmak gerek. Ama deneyip tecrübe kazanmak en iyisi.
