Ironwood Electronics
Ironwood Electronics has been the go-to source for advanced adapters, sockets, and modules. Our adapters convert package and pitch between devices, our modules offer complete fully tested assemblies for component replacement and upgrade, and our sockets allow for complete component and assembly testing - from new silicone characterization and validation, all the way thru burn-in and high volume automated testing – always with the highest performance and lowest possible footprint in the industry. Ironwood brings a combined knowledge of hundreds of years of engineering and manufacturing expertise, all under one roof in our state of the art 25,000 sq. foot facility just outside Minneapolis, Minnesota. Combined with our recent acquisition of the Grypper socket line, our continuous new product development demonstrates our on-going commitment to both our customers and the industry we serve.

Grypper G35 / G40
*Package-size PCB footprint: Since the PCB footprint of Grypper is identical to the package, only one PCB design is required, enabling a seamless transition from test and validation through production and reducing overall cost of test*Low insertion force: Unique contact design reduces the insertion force required to insert and retain higher-ball-count packages safely and securely within the test socket*Oxide cutting wipe action: The contact design wipes the side of the solder ball during insertion, breaking through solder oxides ensuring a good electrical connection between contact and solder ball*Signal integrity: A short signal path achieves low inductance and low insertion loss, providing a nearly invisible electrical connection*Test socket has solder balls attached: The G40 contacts have solder balls reflowed onto the contacts to ensure reliable solder volume at the PCB to test socket solder interface.

Probing & Analysis Adapters
No matter how well designed a circuit is, there is almost always a need to hook up test instruments to it to verify function, look for bugs, or baseline performance. As IC packages become smaller and pin counts grow this becomes harder and harder. probing adapters are required to alleviate this de-bug problem. Many different types of adapters fall into the test and debug category. The common feature is that they bring the signals of an IC out to a format that is easy to interface with test and analysis equipment.

BGA SMT Adapters
Giga-snaP™
Giga-snaP™ 0.75, 0.8, 1.0, and 1.27mm pitch BGA Surface Mount Feet Adapter line of products provide an inexpensive and reliable method for attaching BGA chips to target board. The product line consists of patented female sockets with machined pins epoxy over-molded into an assembly that matches a particular BGA pattern. The epoxy over-molded female BGA socket is soldered to a PCB using standard soldering methods. A corresponding male pin BGA adapter, to which the user attaches their BGA chip, is plugged into the female socket on the board thus interconnecting the chip and the system is ready to go. The SMT adapters have the same solder ball types as the chips they are emulating. These adapters have less than half of the insertion force of competitive adapters, shorter electrical path for highest speed, and can be solder reflowed numerous times. A complete description and drawings of Giga-snaP™ 0.75, 0.8, 1.0, and 1.27mm pitch BGA Surface Mount Feet Adapters can be found at the tables shown below.

Package Converters & Fix Adapters
Package converters provide an electrical and mechanical conversion from one package type to another. We use gold plated interconnects for our pin and through hole converters. Ironwood Electronics offers solder column adapters as a solution for leaded SMT packages such as QFP, PLCC, SOIC, SSOP, and TSOP. This is an excellent choice when you have a PC board in production that needs an upgrade or you need to replace an obsolete part.

Silver Button Sockets
For BGA, QFN, or LGA applications, GTP contact technology provides >94 GHz signal speed and can additionally be used in high cycle life applications such as ATE. These sockets support pitches from 0.2 mm to 1.27 mm. Ironwood's GT sockets are ideal for prototyping and testing almost any BGA device application. These IC sockets provide excellent signal integrity yet remain cost effective. Innovative elastomer interconnect technology that delivers low signal loss (1dB at 94GHz) and supports BGA packages with pitches down to 0.2mm was utilized in these sockets. GT BGA sockets are mechanically mounted over a target system's BGA lands using mounting and alignment holes at proper locations (page 2 of the individual socket drawing shows recommended PCB layout information). These low-profile sockets are only 2.5 mm per side larger than actual IC packages (industry's smallest footprint).

Smart Sockets
Ironwood Electronics extended its high performance socket product line with smart features. Sockets are typically rated for 2K to 500K cycles. How do we know if the sockets are used for 100K or 200K insertions? Solution is electronic chip insertion counter. Our sockets can be integrated with electronics counter into the compression mechanism of the socket lid. A push button is exposed on the compression plate. Every time a chip is compressed, push button is actuated which in turn activates the electronic circuitry inside the lid. These activations are counted by the counter IC and displayed in LCD. Let’s say a contact element is rated for 2K insertions. After 2K insertions, this contact element will be replaced by new contact element. Now, the counter has to start the counting from the beginning. To achieve this function, a reset option is included in the electronics circuitry. When reset is actuated, LCD display will go to “0”.

GHz Elastomer Sockets
Ironwood’s GHz BGA & QFN/MLF sockets are ideal for prototyping and testing almost any BGA or QFN device application. These ZIF sockets provide excellent signal integrity yet remain cost effective. Innovative elastomer interconnect technology that delivers low signal loss up to >40GHz and supports BGA or QFN/MLF pitches down to 0.3mm was utilized in these sockets. GHz BGA sockets are mechanically mounted over a target system’s BGA lands using mounting and alignment holes at proper locations (page 2 of the individual socket drawing shows recommended PCB layout information). These low-profile sockets are only 2.5 mm per side larger than actual IC packages (industry’s smallest footprint). They support IC devices with body sizes ranging from 55mm down to 1mm. Larger body sizes may require a backing plate. If the backside of the target PCB contains capacitors and resistors, a custom insulation plate with cavities cut for those components can be designed. This insulation plate sandwiches between the backing plate and target PCB.

Socket Accessories (Thru-Hole Options)
The male pin adapter consists of standard high temperature FR4 with pressed in terminal pins and threaded inserts for mounting the socket. The top side of adapter has gold plated pads to receive socket interconnect and the bottom side has 0.006″ to 0.018″ diameter pin tails. These pins can be soldered to the plated thru holes in the target board. Then socket can be mounted to the threaded insert.
