It just baffles me as to why a vendor would use, of all things, an arrow as a trademark in the first place. Then stick it on the oppossite side of another marker to boot! I swear, sometimes the way some parts are marked, it's like the manufacterer i

Deni, This looks more like webbing and not flux residue. Webbing is caused by not enough flux to protect the surface resulting in oxide webs sticking to the board surface. The insufficient flux can be caused by: - Weak flux foam head - Air knife p
