can soldermask + paste keep a package from shorting to vias?

-

i received board oshpark.com did not have tented vias under ic package has exposed pad on bottom of it. enig plating visible on edges of holes, instead of complete solder mask drill.  i'm wondering if thickness of solder mask around hole, in combination solder paste holding chip down keeps package high enough off board exposed pad not touch vias?  i've done quick , dirty continuity checks between ground pad , vias on bottom under chip, shows no short, may because ep wired differently or something.

should safe in assuming nothing shorted if continuity test shows negative?

ooh, poor mix of design and/or parts selection there.
still, if signals not showing being shorted gnd (or whatever signal pad - read datasheet today had chip pad @ 3.3v) might okay.

¿conocéis este proyecto? fvdw-sl 15.3 para raspberry pi. convierte la raspi en un nas. http://plugout.net/viewtopic.php?f=31&t=1880 llevo tiempo intentando encontrar la forma de hacer que una de mis raspberry se comporte como un nas. configurando samba, minidlna, transmision, ftp, nfs, etc. pues con esta distribución lo tengo todo hecho. lo instalé ayer y me tiene soprendido. ahora mi raspi es un nas, hecho y derecho. caracterísitcas. - interfaz web. que cambia en función de si eres el administrador o un usuario. - gestión de usuarios. puediendo dar distintos permisos carpetas y funciones. - gestión de carpetas - vpn - ftp - nfs - webdav - varios servidores dlna como minidlna, townky, etc - varios gestores de descarga como transmision, mldonkey, etc - gestión de periféricos usb como impresoras o webcam. - gestión de cron para automatizar procesos. - creo que se basa en arch linux. por cierto, estoy creando una tarea para que me exporte un archivo txt del dis...

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
