There’s no wrong way to baste a quilt so long as your method holds all the layers of the quilt “sandwich” together securely throughout the quilting process. In other words, don’t be afraid to adopt the method that’s easiest for you. After all, a finished quilt is always better than a perfect quilt, and it’s all the little idiosyncrasies that add charm and individuality to every project. Modern times call for modern measures, however, and today’s quilters are all about finding the simplest means to the end. Thread basting is the oldest method and the one your great-great-great grandmother probably used when she stitched those quilts of necessity. When most people think of quilt basting, they picture the thread method that uses long, loose stitches to hold the three layers together securely. 1" pitches).There’s a quilt-basting technique to suit every quilter, from the most meticulous sewist to those who just want to get the process over and done, including: Helps prevent damage to exposed header posts (.050" &.Aids blind mating, where the installer or end user cannot see the connection to be made, and has to feel for the connection.Allows multiple connectors to be used on one piece of equipment, customers may choose to use different polarized circuit sizes, such as a 10 and 20 position to clearly identify which orientation a mating PCB is designed to plug together.Eliminates connector mis-mating, which depending on where power is routed can avoid costly damage to OEM equipment.All options include shrouding and keying designed into insulator on the male and female mating halves. Customers may choose from a range of pitch sizes, each having their own method of assuring that mating headers and sockets may only be plugged together in the correct way. GCT's range of polarized connectors for board to board applications offer a variety of options. GCT's gold flash plating offers a good balance between the advantages of gold and the lower cost of tin.Gold offers excellent conductivity, low resistance, excellent corrosion resistance and durability - high cost.Tin offers excellent solderability and conductivity, but low durability - low cost.Resist migration of materials between the base material and finish platingįinish plating is available in variants of gold or RoHS compliant tin.Metal plating layers are added to the core pin or contact to allow or improve:Īll pins and contacts are under-plated with a layer of nickel to: Core header pins & receptacle contacts are manufactured using high quality copper alloy, this material isĬost effective, easy to manufacture with good electrical properties. This section covers connector contact material and plating within GCT's board to board connector range. GCT board to board connectors are available in the following pitches: That said, the small ranges cater for the most basic designs, such as PCB's mating in co-planar, right angle and parallel orientations. You're more likely to find a physical solution in the numerically larger ranges. ![]() there are sixty seven 2.54mm connector options and nineteen 1.00mm options, so depending on your design Other physical constraints - does the range offer the connector types to achieve the design you require? e.g. However, GCT offer numerous low profile connector options across all pitches.Ĭurrent carrying capacity - the smaller the header pin size the lower the current carrying capacity. Generally using smaller pitches allows lower connector profiles and thus lower printed circuit board stacking Space constraint - The smaller the pitch, the smaller the connector. There are numerous considerations the hardware designer must balance in choosing the correct connector pitch: Pitch refers to the spacing between individual pins. Pair, one mating and unmating is described as a "mating cycle". Pin headers (male) and socket (female) connectors are used as a However, in most applications the printed circuit boards are required to be connected and disconnected to simplify assembly and allow design flexibility. This approach may be used in a "fit and forget" solution where no mating cycles are required. This connection can be permanent in the case of "hard soldering" (soldering a pin header to the PCB at both ends). Other features include locating peg options, shrouding, polarisation, keyed or elevated headers and sockets, with completely bespoke solutions possible.īoard to board connectors are designed to connect printed circuit boards together without a cable. Pitches ranging from 0.8mm to 5.08mm, selectable pin lengths, and insulator heights. With over 160 standard parts in the GCT Board to board range and a large element of customisation also available. High quality and competitively priced PCB connectors for any situation. ![]()
