Disclosed are an improved card connector and a method of mounting the same on an associated printed circuit board. The card connector comprises an insulating housing having contact pieces fixed therein and a shield plate detachably fixed to the surface of the insulating housing. Such a card connector can be mounted to the associated printed circuit board by: soldering the leads of the contact pieces to selected conductors in the printed circuit; and then soldering the leads of the shield to another selected conductors in the printed circuit. The two-step separate soldering permits the contact-to-conductor solderings to be checked in the absence of overhanging grounding leads. Therefore, incomplete or defective solderings, if found in the contact-to-conductor solderings would be fixed with much less difficulty than the cluster of overhanging and underlying lead-to-conductor solderings.
