Frequently asked questions Question 1 Question 4 How do compressive connectors hold in position Are the shapes of the connectors adaptable to my needs Answer 1 Answer 4 In order to assemble a compressive connector, it is rst inserted in a In many of our circular connectors we have designed a chamfer in order cavity in the phone cover. The compressive contacts are designed in such to accommodate for the design of the device. Typically our products are a way that they are compressed to the PCB board when the cover is used on the edge of the device. Deviating geometries can be studied assembled to the phone. upon request. Question 2 Question 5 Should I be using Pick and Place pads Is pick and place possible for compressive connectors Answer 2 Answer 5 In case of non-gold-plated PCB pads on the board side, so-called pick Our compressive connectors are supplied in embossed tape according to and place pads can be used. These are tiny, square gold-plated pieces of EIA specications. This allows for robot assembly of the connectors in the sheet metal, which can be soldered to the board, and provide gold covers. plating on the PCB board where it is required. Question 6 Question 3 What are the advantages of the isolated switch Is the signal transmission in compressive style connectors reliable Answer 6 Answer 3 Typically, switching is performed using two contacts on the ground Compressive style connectors are as reliable as SMD type connections ring of the plug. By detecting the shortcutting of these contacts from a signal transmission point of view. The gold-plated interface when the plug is inserted, the device can detect that the plug is provides a stable and reliable connection under all conditions. If you take inserted. However, currently there are two kinds of plugs in the market. the added robustness and eliminated risk of solder joint breakage into The position of the ground ring differs in these two versions. In order consideration, compressive style connectors are more reliable than SMD to be able to provide plug detection, the switch has to be electrically connectors. This is due to the fact that these connectors do not require isolated from the plug. This is called an isolated switch. The benet of soldering. During large shocks (which typically cause solder joint breakage the isolated switch is that it can safely detect the plug independent of in SMD connectors), the compressive style connector contact allows the position of the ground ring. movement to accommodate for the shock and quickly returns back in its old position without any damage to the connector or the PCB.
