Thru-hole headers in tape and reel packaging


So you’ve been searching for a component and finally manage to find a part that meets the requirements perfectly, only to discover that it cannot be packaged appropriately for production processes, how frustrating!

GCT recently rose to the challenge with the BG041 series board to board connector through its custom packaging options.  Thru-hole 8 pin header connectors with 2.54mm pitch are only available in bulk packaging, a standard option in the industry for this type of product.


The customer required tape and reel packaging so that parts could be vacuum pick and placed for automated assembly.  To make things more difficult, a small cavity with a mating post height and tail length of 1.5mm was also required to house the part, tricky to say the least for tape and reel..

As a result, GCT now has the ability to supply thru-hole headers in tape and reel packaging.  By designing and tooling a custom tape and reel cavity to allow the thru hole pin header to be picked and placed in the surface mount process, GCT has demonstrated its capability and flexibility in providing a solution for the customer.


For any custom packaging requirements on board to board connectors or anything else, we’d love to hear from you.

You can find GCT’s full range of board to board connectors here, along with more information on PCB connector packaging here

PCB stacking connectors above 50mm

Planar PCB connection when the PCB spacing is greater than 50mm is a challenge using traditional, economical elevated pin headers and sockets as the length of the pins can cause distortion either during the product manufacturing process or in the final assembly process.

An alternative option is to utilize a low cost PCB in place of the elevated pin header.

PCB stacking connectors above 50mm

The picture shows an example from GCT’s 2.00mm pitch board to board connector range. Receptacle connectors are mounted on both horizontal PCBs.  BF100 on the uppermost PCB and a BF120 on the lower PCB.

On the vertical PCB the uppermost connector is a BF060 with the lower part being a custom shrouded version.

This arrangement can be made using parts from GCT’s 1.00, 1.27, 2.00 & 2.54mm pitch ranges.

Custom PCB header with supporting feet

PCB header with supporting feet

We’ve been working with a customer who needed a customized stacking header with an extended height but tiny footprint to stack two PCB’s in parallel orientation. We offered an elevated header from our 1.00mm pitch board to board connector range, this looked like a perfect solution, but was prone to tipping during the solder process, a problem magnified by the tiny contact pitch.

To help balance the connector we molded a custom insulator and produced a PCB header with supporting feet.  The feet were designed to strategically to work around existing components on the PCB, which enabled the customer to avoid a PCB re-design.

Turnaround time on this design was seven to ten days.

Another problem solved with a clever solution from GCT’s custom connector team!  We can offer a wide range of custom PCB header solution, from simple modifications of existing parts all the way up to a bespoke PCB header solution.

If your PCB header requirement seems out of the ordinary speak to GCT, our low tooling charges and minimum order quantities might surprise you.

SIM card dimension guide

SIM card dimensions and release dates

Here’s GCT guide to SIM card dimension and thicknesses.  We offer a large variety of SIM card connectors which accept the three main SIM card types.

Mini SIM, also known as 2ff or 2nd form factor was introduced in 1996 and has been the standard type for many years, there are a wide variety of connector products in the market, but with the emergence of Micro and Nano it’s now a mature product.

2003 saw the introduction of the Micro SIM card, also known as 3ff, or 3rd form factor. Micro SIM is the same thickness as Mini SIM at 0.76 mm, however it offers a much smaller overall package, the contact area remains exactly the same, but size is reduced by more than 50%.

Nano SIM was introduced in 2012 and is becoming more and more prevalent in the market. Nano SIM is also know as 4ff or 4th form factor.  It’s even smaller and thinner than Micro SIM, with a 108 mm footprint, vs. 180 mm for Micro. However it is very small and can be fiddly for end users to handle.  We see that Micro SIM has longevity in the market, as although smaller it is more easily handled by the end consumer.

Global Connector Technology offer connectors for every SIM card type, with a variety of different styles, such as push-pull, push-push and hinged.
