| 1 - What does CRIMPFLEX stand for ? |
|
Patent & trademark. The Crimpflex connection system complies with the most rigorous electronical & mechanical requirements. The crimping of the contacts is obtained by piercing the conductor in 6 points. This ensures excellent mechanical retention by 2 points & electric contact by 4 points with the lowest possible contact resistance.
|
| 1b - What is the difference between OM & OMH housings ? |
|
OM has little holes to accept contacts on one side of the housing.
OMH has little holes on both sides of the housing.
|
| 2 - What is the CRIMPFLEX product range ? |
|
Nicomatic offers male pins & female contacts with a pitch of 2.54mm and 1.27mm (NEW!), the corresponding housings, male solder tabs (standard, standard short, retention, retention short, double retention and long), flexcable jumpers (in male/male, male/female, female/female and double row configurations), manual & pneumatic presses to crimp contacts (the Crimpflex connector system is one of the few connector systems available for flat conductor products, especially membrane switches, printed ink circuits, flexible PCBs and flat flexible cable (FFC jumper assemblies).
|
| 3 - What type of circuit can be crimped ? |
All types of flexible circuits whose thickness ranges from 50 micron to 500micron, please contact us for other thicknesses.
|
| 4 - Is it possible to crimp contacts with a 1.27mm pitch ? |
|
Yes. A new product with 1.27mm pitch is available upon request.
|
| 2b - How many contacts can be crimped in one press stroke ? |
|
On our standard machines (manual & pneumatic presses) it is possible to crimp up to 25 and 36 contacts in one press stroke. On the new 1.27mm crimping press, it is possible to crimp up to 50 contacts in one press stroke.
|
| 3b - What is the production cycle rate of the pneumatic & manual presses ? |
Manual press : 350 cycles / hour (up to 420)
Pneumatic press : 1 500 cycles / hour (up to 1 800)
|
| 5 - What is the energy used to make the crimping press work ? |
10500-SA(P):
The energy is pneumatic only (no electrical) :
6 bar (hydropneumatic)
Effort : 1 800 kg/cm2
Reel contacts speed : 5cm/s roughly
Capacity : 30 cycles per minute
|
| 6 - Does the standard machine configuration allow to crimp square male contacts ? |
Yes, there is a pneumatic press made for square male contacts under P/N 10500-SAP. Please contact us.
|
| 4b - Can you adjust the air pressure of the pneumatic press ? |
It is possible but not recommended. The risk is to break the machine or lead to malfunction. NICOMATIC presets the press at 4 to 6bar air-pressure.
|
| 5b - Is it possible to crimp all the male solder tabs with the male toolings ? |
|
Yes, except for the male solder tab (ref. 11612) which must be crimped with the female tooling. Male contact (ref. 13595) is also crimped the same way.
|
| 6b - Can a customer crimp the CRIMPFLEX contacts with any crimp press on the market ? |
No. In order to get the perfect crimping of your contacts you need to use the CRIMPFLEX presses.
|
| 7 - What is the difference between a male solder tab & a male contact ? |
A solder tab be soldered or fit into I.C. sockets or wipe contacts whereas the male contact will mate with most female connectors designed to accept a 0.635mm pin header.
|
| 11b - What is the difference between a low interface force female contact & a hish insertion force female contact ? |
|
The high insertion female contact (ref 10025) is recommanded for the automotive market thanks to an excellent resistance to vibrations.
A lower number of mating cycles results from increased retention for high vibration applications. The low insertion female contact (ref. 11506) is recommended for up to 500 mating cycles when using gold plated contacts and up to 50 mating cycles for tin plated contacts. Ref 10025 is suggested for up to 10/15 cycles. Beyond, use rather 11506 part number.
|
| 8 - Are the Nicomatic housings compatible with the standards of the market ? |
|
Yes, they are compatible with all existing standards.
|
| 9 - Do the housings allow polarization & locking ? |
|
With 11 product references, the product range of Nicomatic is one of the broadest on the market. Some housings allow polarization, other allow locking and a number offers both possibilities.
Consult our catalogue page 19 to 25.
|
| 17 - What is the difference between OM & OMH housings ? |
|
OM has little holes to accept contacts on one side of the housing.
OMH has little holes on both sides of the housing.
|
| 10 - What is the cable used for flexcable jumpers ? |
The flat cables used for Nicomatic flexcable jumpers equipped with Crimpflex connectors are made of flat copper conductors both sides adhesive bonded to aluminium foils.
|
| 11 - What is the operating temperature of the Crimpflex connectors for flexible circuits ? |
- 55 C to + 150 C, (- 67 F to + 302 F).
|
| 7b - What is the direct current rating per contact ? |
|
3 A (Dc) in standard or 5A (Ac). The contacts have also been successfully tested at 5.5 A (Dc) in a number of applications by our customers.
|
| 8b - P3 & P7 styles (FFC Card Cables): what is the difference? |
P3 cables are used for mating to ZIF sockets and the P7 are for soldering to a PCB.
|
| 9b - Is it possible to connect a flatcable with a AWG cable? |
Yes. NICOMATIC provides an interconnect solution which allows to associate the two systems:
- 2SLxx (female housing)
- 1SMxx (male housing)
- 12472 (female contacts)
- 12471 (male contacts)
|
| 1c - I have a jumper and would like to place a connector that allows me to end with discrete wire. What do you have ? |
We provide a solution from flat cable to discrete wire with the appropriate connectors. Contact us or please refer to PCB connectors catalogue (version April 2007) on page 25.
|
| 2c - Is it possible to crimp 11612 & 13595 contacts with a 10025-MO-M press ? |
No. As the cutting part is as long as that of female contacts (2.6mm), you need to crimp using a female tooling for the male 11612 and 13595 contacts. It is an exception.
Therefore, please either order a 10025-MOF press or change the tooling on your 10025-MO to the female one.
|
| 3c - Whiskers: is the tin plated area matt or bright ? |
Our tin-plated is bright.
|
|
| 4c - Whiskers: is tin plated area nickel underplated? |
Yes. There is a minimum of 1.27µ of nickel underplating.
|
| 5c - Has Nicomatic fulfilled any tin whiskers
growth test on tin plated parts (eg. JEDEC JESD201)? |
There is no test made directly on the parts but we passed the
JEDEC JESD201 on the electrolical bath (the process) to prevent whisker
growth risk.
|
| 6c - What is the purity of gold on the contacts surface for 10025-31 and 14106-31 female contacts |
Au: 99,35 -99.55% / Ni: 0.10 - 0.15% / Carbon: 0.20 - 0.30% / Hardness 110 - 170 VPN / Density: 16.5 - 17.5 g/cm3.
|
| 7c - Can 1.27mm Crimpflex pierce the same thickness range as the 2.54mm? |
The piercing part of the 1.27mm crimpflex contact is slightly higher than 2.54mm (1.2mm vs 1.1 mm) and a lot larger so it can pierce thicker subtract than 2.54mm crimp contact (1.27 crimp contacts is more robust and won't bend as the 2.54 crimp contacts) for example you can crimp 0.6mm PVC for EL.
|
| 8c - What is the maximum current rate per contact that Nicomatic can guarantee? |
Due to the way we crimp thru the conductive layer, we get excellent results. At 3A the temperature goes up. For example with 7 contacts at 3A for 1hour 54 cable temperature goes up by 84°C if out side temperature is 30°C global temperature is over 105°C. So you need to choose carefully your cable (our cable polyester is guaranteed at 110°C, and we can provide polyimide cable that goes up to 125°C according to customer appliance).
Nevertheless having 10 contacts at 3A will work perfectly but temperature will be high. |
| 10b - What is the maximum thickness you can crimp with standard 2.54mm crimpflex contacts? |
We can crimp up to 0.4 cm (2 * 0.2cm, regular cable) with some press machine adjustment.
|
| 9c - Can a Crimpflex FFC jumper hold at 120°C during one to two hours? |
The contacts hold at 150°C and FFC at 105°C. You need to select a polyimide material for your FFC as the temperature characteristics are much better:
-55°C to +105°C for Polyester cable
-55°C to +125°C for Polyethylene naphthalate (PEN)
-60°C to +150°C for Polyimide cable (higher temperatures achievable upon request)
|
| 13 - What is the new OJxx and OJHxx CRIMPFLEX housing? |
The new OJ and OJH housing offers an extra mechanical protection on both sides of the latch to prevent it from breaking or tearing in vibration environments. It also has an other new feature with the addition of 4 chamfers for a better insertion guiding. It gives extra features comparing to OL and OM housings available in the range.
